Coreplayer Audio

I've set my Coreplayer up as per the posts elsewhere in the Athena threads and the video quality is almost perfect now.
I'm using 320x240, DivX 6, 500-700KBps constant bitrate files.
Stereo MP3 audio. 96kbps or 128kbps.
After 10 mins of playback the audio slowly starts to lose sync (it plays fine on my PC).
Has anyone got any ideas what I need to do to stop the audio from losing sync?
Any help greatly appreciated.

hi
when you say "outof sync", does this mean that the audio is fine but the video is not "in time"? if yes, that's exactly what i was going to ask in the forum =) but i'll be trying the parameters you set. i've been meaning to ask the "optimized" setting for this application.
cheers

Yep, that's exactly it. It starts off fine, then ever so slowly the video gets ahead of the audio.
I've 'fiddled' with just about every setting I can think of within Coreplayer but have yet to find a solution.

well, at least your video gets ahead. for me it's the other way around...the video is late yet the audio sounds perfect =)

ive already asked this question. with no replys. ive tried every setting and format possible. still loses sync. it doesnt matter if its from the sd card micro drive or streaming. it still loses sync. ive even tryed disabling the auto scaler and running tcpmp over clocked. still loses sync. im a a loss. if you find a solution let me know.

I guess we need to wait for the next version of Coreplayer which will (hopefully) be released on the 18th of June. It supposedly fixes some of the ATI issues.

I am so sick to death of this subject!! Not mad at you guys, but at ATI/AMD. This has been an ongoing issue since September last year when the TyTN was released with the ATI Imageon chip, and due to no input or support from ATI/AMD, Corecodec cannot fix this issue as it's to to with the Imageon hardware.
Bottom line is find the settings that work best for you. For me, I find TCPMP v0.72RC more stable and versatile than CorePlayer v1.04. Also set Video driver as Imageon (NOT Imageon decoder!) this yields best performance and visual quality 'during' playback.
If you're using DVD-Rips use the above setting, but if your playing/stretching QVGA 320x240 on your Athena, then Rawframebuffer mode is even more stable in the GUI, but lacks the ooomph of the Imageon driver, which to some extent might well eradicate your lipsync issues.
One more test folks. Play your video whilst your Athena is pluggen in to mains power. See if the lipsync is still out. If it is make manual adjustments in the A/V offset in TCPMP under Advanced.

Ive got the exact same problem on my x7510 i start playing it and slowly the video will go ahead of the audio and its out of sync very easy to detect when your viewing a lecture. ive tried all kind of video players

How cam that you can use it.
I'v tried 0.72 version as well as 0.81 and both give me the "crash.txt" error while starting TCPMP.
Oh, you are using CorePlayer not TCPMP, right?

im using coreplayer the latest version becuase tmcp as you said keeps on crashing, (for me too).
With a hard reset playing even a video in windows media player still gives a audio lag. Its so bad, now i don't care about quility just let me have a video with audio i don't care how bad the video looks like.
Does anyone have any solution? ive tried all kinds of "video output" settings and it still gives audio lag (even raw framebuffer)

FINALLY! ah found it after lots of searching of google and forums and sites...
its -400ms and its perfect thought the whole video..
(Note: the best method that i use to see if its in sync is to watch a lecture and then watch their mouth real careful and you'll see that -400ms gives the best results )

What is this -400Ms?

-400ms is -400 milliseconds as in time. The minus sign means "start playing the video 400 milliseconds ahead of the audio. Its perfect for core player put all the settings on max just take acceleration and dithering off. And it plays a DVD rip perfectly no conversion very sweet on its 5 inch screen
If you don't know put the -400 in the settings next to "manual A/V offset +/-" and just type in "-0.400"

I am confused, because on the other thread, you mentioned it did not work.

it does for like 5-10 minutes then audio gets our of sync

Coreplayer plays flv files, yes. There's no need to separately install additional component. It benchmarks better than TCPMP in my test.

WMP & Coreplayer on X1

Hi,
Got my Xperia X1 the other day, I have got Coreplayer Mobile as well as the WMP on the phone. I have copied the videos I took with my Nokia N95 to the memory card Ive got in the Xperia.
However when it comes to playing them WMP will play them but it stutters alot with the sound being ahead of the video. In coreplayer there is no video only sound.
Any of you guys got any suggestions to get the video playing smoothly. The videos are .mp4.
Thanks

Try to set in Videosettings QTv Display, here I get a picture and it works ok, not the promissed 30 fps but arount 20 fps with a HDTV Movie.

Then I don't have any more ideas. Perhaps it'll help trying TCMP instead of Coreplayer?!

Found this on Coreplayers website:
CE/Windows Mobile/PocketPC/Smartphone

Is anyone running Coreplayer? Is there anything better?

I've tried to find a resolution/bitrate which gives me smooth video without stuttering and dropouts. I've tested on CorePlayer with DivX and native mp4 codecs.
With a resolution of 400x240, 25fps, 1100kBit/s I get a picture without dropouts and a benchmark around 105%.
If I go higher in resolution I start getting dropouts.
I've set the CorePlayer to Microdrive mode and doubled the size of the buffer to increase the speed when reading from the memory card.
I've tried to copy the clip to the phone memory, but with the above settings I see no difference.
My conclusion is that if you want a smooth picture, don't go above the mentioned resolution. It won't give you that crisp picture, but I get more annoyed when the film is stuttering than getting a HD resolution on a 3" display.
I have no problem seeing mp4 on the CorePlayer though. But if I uncheck the "TyTN II driver mode" in QTv Display settings, I get only sound, no picture, despite the MSM7200 chipset . Don't know if the Nokia's format differs from the one I have used (Cucusoft Ultimate DVD).
Is there anyone else who manages getting a higher picture quality without any dropped frames?

Got this from the Coreplayer forums:
'We are on the verge of the v1.3 bug fix release that addresses many of the current issues including those diamond users running WM 6.1...... however it does not address the QTV issues since there is nothing we can control there other then to express our dismay to both HTC and Qualcomm for not opening up the GPU.
Hey... we've been here before.... lets hope for a more open solution soon enough.'
I wonder what SE's position is on this? Apparently it's meant to have a decent GPU but what's the use if we can't use it? I know one or two people here have contacts with SE - anybody wish to find out?

Praying for hardware supported video playback...

but they said that X1 uses ATI GPU not Qualcomm!
Another lies from SE?

Hey guys, i know this is abit off topic, but has any of you guys had the problem were you install core player, then play a video, and then you exit and go back into it and you the the message "cannot validate the serial number/user ID"? i have uninstalled and reinstalled heaps of times, tried different serial numbers, but it happens all the time use it once, and then the message comes up when you go back into it.

Says who, I haven't seen any info about it, any links please.
Of course the qualcomm chip has indeed 3D hardware acceleration but I don't know if it is ATI.

unbelieveable how unprofessional are they! 1st the RAM debate, and now this; not to mention that bad launching and availability.

It is rather disappointing. Even the fish panel is hardly super smooth, leading me to wonder if even that uses the GPU acceleration.
I really do hope SE allow and encourage developers to tap the GPU of the X1 otherwise its little better than all the other WM phones.
I have hope that someone with a reputation like SE will see the sense supporting the developers. The "write something for the panel" is not good enough. The radio is a panel and as the panel is like the home screen, anything on it is turned off when I navigate away from it including the radio.
I really do hope they do not turn out to be as bad as networks like T-Mobile which can't be bothered to support HTC rebranded phones even if its got their name stuck on them.

after using it for 3 days it is now clear that the panels just use low res screenshots and no live data. They dont even update them, i live in germany and when accessing panels the screenshot says New York etc until it finally updates.
So for the panels just being low res screenshots (that must be only some KBs per panel) the performance is horrible and laggy. Cant believe they use any form of hardware acceleration for that either.

If the video is encoded in H.264 it's going to be lagging full on. Half of the frame will get dropped. Playing 720x400 24FPS at 1Mbps encoded with XviD on the other hand is smooth and not a single frame is dropped. I've tested this with TP.

Does anyone know how to change the default streaming video player to Coreplayer?
It's very annoying when browsing and the Streaming Player kicks in rather than Coreplayer. I've associated 3gp, mpeg4, etc. with CP but doesn't seem to make any difference.

Video playback problems - Coreplayer, TCPMP : SOLVED/SOLUTION

PROBLEM SOLVED - CONCLUSION OF THREAD updated 9/3/10:
1). Coreplayer and TCPMP don't work well on my device when playing back avi (divx/xvid) because they don't support hardware accelaration, although others seem to have no problems which still confuses me. Playback is juddery dropping many frames. I have tried Shasaraks settings (which are the best) and all others with no luck.
2). Because WMP and the HTC player don't support avi (divx/xvid) converting to mp4 is the only option for me.
3). CONVERSION: I have tried many converters including: TMPGEnc.XPress, handbrake, xvid4psp, mediacoder and others. The ones that do work well for the HD2 all have the same problem and that is a delay in audio putting speech out of sync when played back on the device. Even when playing back avi's in coreplayer i had to manualy adjust the sync.
The only converter that works well and is fast and can put the audio in sync for playback on HD2 is winmenc available here (freeware) http://winmenc.blogspot.com/
Download my profile which has the audio sync tweak already in it (thanks to Kr00ton) and put it into the profiles folder. I have tweaked Kenkiller's original profile, see here for info: http://forum.xda-developers.com/show...7&postcount=38
I have changed Kenkillers profile from 2000 to 1000 kbps to save file size and have also got rid off the 2 pass encoding to save time (and lots of it!). You also need to tick FIT TO WIDTH AND SPEED & QUALITY CONTROL AND MOVE IT TO FASTEST. I done various tests and found no noticeble difference to SD videos doing it my way. This speeds up conversion time to around 30 mins for a 700mb avi and keeps the file size about the same as the original.
If you have more time on your hands and or you are converting HD then maybe use Kenkillers original profile, although i converted HD stuff in my profile and it looked great. It all depends if file size and conversion time is an issue for you.
4). For some reason the HTC player still judders for me, i'm pretty sure it didn't do that in stock rom 1.44 but it certainly does on my 1.66 ROM leaving only WMP that performs perfectly It's a shame that it isn't very finger friendly for srolling through the video etc but i'll live with that.
I can only report my findings and experiences, you may not have the same issues i have had. Conversion may wield different reults on other OS's. I'm using windows 7 64 bit and can confirm that when i used winavimp4 converter on xp it was perfect but used on windows 7 it puts audio out of sync. Having said that it is without a doubt the fastest converter i have come accross converting a 700mb file in around 10 mins on windows 7 64 bit. It was around 30 mins on my old xp machine.
5). I can now relax and enjoy my films on my HD2, which is the main reason i bought it!
ORIGINAL 1ST POST
I bought this phone because of its screen. I watch movies on my long journeys to work and i'm getting increasingly frustrated with the phones poor performance on playback.
Coreplayer judders with many dropped frames no matter what settings (tried shasaraks direct draw settings) or version of coreplayer i use and disabling sense and using plane mode makes no difference whatsoever. It will play flawlessly for a while then judder then be ok then judder on and on...
So i decided to convert to mp4:
coreplayer still has poor performance. HTC player was ok but since upgrading to 1.66 it's performing worse than coreplayer now (yes, i did a hard reset after flashing)
The only player that works is wmp. I now have some questions:
1). Is there an option in wmp to sync the audio manualy like in coreplayer? some films are slightly out of sync.
2). are there any other players that work well on the HD2 apart from tcpmp (tried that, same results as coreplayer)
3). CONVERSION:
What are the best settings for video conversion for the HD2? If I can't use coreplayer to play avi this is my only solution and aslo solves the problem of coreplayer not supporting ac3 audio. I'm talking bitrate etc for video and audio. If you are succesfully converting video what converter and settings do you use? PLEASE!
I tried searching but couldn't see a thread dedicated to optimum conversion settings for the HD2.
4). Could the problem lie with my 16gb sandisk sd card? i noticed another thread for the blackstone where a cab was designed to speed up the cards performance by 3 times, is there something like this for the HD2 and would me formatting it to fat 32 make any difference at all to my problem?
This is really winding me up now and i've spent hours messing with settings etc, the one function i really need and it wont perform which i find very surprising for a phone that has this super fast snapdragon processor.
PLEASE HELP ME
END OF ORIGINAL POST, PROFILE FOR WINMENC BELOW

1) no
2) none even close to that
3) can't tell, as I don't really do it much, coreplayer works well for me
4) could be, as coreplayer works well for me.

Could well be the card, as it sounds like it gets to the end of a buffer, buffers, then continues, causing the lags.

I know that reporting my own experience is of relatively low usefullness to you as it's not step by step instructions on how to solve your problem, anyway:
1) I use TCPMP to watch AC3 audio-encoded series like frasier
2) I use Coreplayer to watch non AC3 encoded series like sex and the city
3) tcpmp is slower than coreplayer for those videos that coreplayer CAN play, I get ~120% bench for SATC in coreplayer and ~90% in tcpmp, but nonetheless I can watch everything (...that I tried until now) in tcpmp without noticing the slightest issues, and I always "zoom to fit screen", which means the video fills the entire 800x480 resolution
4) I watched videos on my old ipaq 214 as well, sure we're talking about a different device, but we're aso talking about a device with a 600MHz cpu and without an accelerated graphics subsystem (and I do have chainfire patch for the graphics subsystme of my hd2)... well I only used tcpmp on the 214 and no issue there... and I watched the whole Death note series, crappy bench results but no issues with jumps in the video
5) I have a 16gb class 2 sandisk microsd, and despite it being class 2, I get ~7mb/s transfers both ways in the sd reader of my laptop, so if we're using the same memory card, that should not be the problem...
6) probably you watch "heavy" encoded movies?

Look at this:

Important ist to set the audiodelay.
With this solution you can get very good *.mp4 Files with audio in sync playable with Manila album or Mediaplayer.
I tried a lot of things but this was the only way to get good video with audio in sync.
Sorry, but english is not my first language.

For coreplayer i'm using v 1.3.5 build 7340 but the newer 1.3.6 build 7427 also performs the same.
What version are you guys using?
Failing that i'll format the card to fat32 to see if that makes a difference and have a look at that winmenc.
Any other suggestions are very welcome

defo not this. I converted a film to the lowest spec audio and video wise and it resulted in 350mb file... It played the same as the 1.2g original!

I used handbreak to convert to MP4 and then used the built in player in sense.
Seemed to be HW accelerated as 45minutes of playback took about 8% of the battery charge and I would expect doing soft decode of H264 would take more than that.
Only downside was waiting 15minutes to go from 720p to iPhone profile in handbreak. I am going to experiment with remuxing
Jim

I have created a preset in handbrake specifically for the HD2 - Let me get home and post it back for you.
have been using this - converted about 20 movies and loaded up around 10 on the HD2 for a trip. All of them played perfectly in HTC album (Looks like it's hardware accelerated). Approx 4-5 hours on a single full charge (around 2 1/2 movies back to back).
Best part - converstion takes about an hour on a 4 yr old laptop - should happen much quicker on new ones.
Source files are all mkv (for Blu-ray rips) or iso (for standard DVD)

please do mate, looks like a nice converter, if you post the sttings you are using i'll give it a bash tonight.
I don't know what is going on with coreplayer, i used it a while ago and it played lovely, about 2 drops in 10 mins. I just tried again, 11 drops in 10 seconds what does this tell us!?!?!?!?

Could also be that you have something running in the background that's using the CPU badly...

This thread is worth checking out for video settings: http://forum.xda-developers.com/showthread.php?t=582122
A converter that is reasonably idiot-proof (although its maximum bitrate is a teensy bit too low, IMO) is MP4ForHD, which you can find here: http://forum.xda-developers.com/showthread.php?t=478050 I think it lets you incorporate an audio delay into the video (thus negating the need to do it in the player).

I've bought Core PLayer and Kinoma PLay but the only one i use to play my videos and series is TCMP, its litter and complete doing its tasks.
I prefeer TCMP.

Is what i thought but no, everything is shut down. Does the same after a soft reset. Disabling sense and using plane mode also makes no difference.
But like i say, soemtimes it works and sometimes it drops like a mother f*****
it's completely random
what i will try is another sd card, i got the 2gig one indoors, i'll put the same vid on that and report back... all rather boring but it's doing my head in and i don't like being beaten

thanks, will take a look

I just don't see the point in encoding especially for a mobile device.
That's iphone madness, not ours
I've been watching videos encoded for proper pc's since when I had my ipaq hx2400 back then, after that I kept doing it with my ipaq 214, and now I am happily doing the same on the HD2. I am sure there's something that's preventing jonbaker from watchgin movies normally, and using an alternate encoder is not a "solution" but a complication. Occam would say the same.
More specific info on file size/length/codec/bitrate/tcpmp-coreplayer bench results/microsd transfer rate (tested with read/write operation in usb disk mode) would be useful.

If memory card access is causing the problem with CorePlayer then you could try increasing the amount of memory CorePlayer uses to buffer. You could also try out these registry settings which sometimes improve SD card performance: http://forum.xda-developers.com/showpost.php?p=5547319&postcount=8

I'm operating entirely on guesswork, so no, no chance at all!!! I guess it needs to still be small enough that there is no danger of running out of memory on the phone, but larger than the default value. Might not make any difference, of course, depends on what's causing the bottleneck.
Have you tried getting CorePlayer to play video and audio in the background and then opening up the task manager to see what the CPU usage is doing? That might at least tell you whether it's a lack of processing power as opposed to something else.

RIGHT i set coreplayer to play in background: BUILT IN TASK MANAGER:
mem - 7.94m CPU sitting around 45 - 65%, then will drop to around 20% then back up to 60%
RESCO TASK MANAGER:
mem - reports 2.68m
don't know why they give different results memory wise don't think resco task manger gives cpu usage
is all that normal?

Coreplayer, Smooth than laggy, and perfect in benches??

Hey guys just got a slick HD2 from Tmobile, and I wanted to check out Coreplayer. I started playing a few WVGA videos with decent bitrate, and towards the first 10seconds video played fine than started to lag and drop frames, then when I skip to a different part, it plays smooth for another 10secs than lags. When I run benchmarks, the video scores 120%.
I am using these settings for optimal playback.
Tools:
>Settings:
>Video:
Video Output: DirectDraw
Video Quality: High
Smooth Zoom: On
Dither: Checked
--
>Direct Draw:
Uncheck Both “Overlay with colorkey” and “Use blitting instead of overlay”
Check “Use device stretching for blitting”
Overlay format: YUY2 (or RGB to enable Dither)
--
These settings give me best visual quality, tell me if there are better settings.
However, the above problem occurs, in many different configurations.
I believe the process priority is the concern here, I think Coreplayer auto ranks up the priority during benches but doesent seem to do so while playing, most likely to conserve battery life.
I was reading a long time ago about a program that increases process priority in Windows Mobile, and was hoping that it may do the trick. So can anyone lead me to the rite softwares???
---Edit: I tryed to change the priority but it is always set to highest, in benchmark mode and in normal playback. Does anyone know what could be the problem.

I think those are pretty much optimal. (RGB overlays are definitely slower than YUY2).
Try putting the phone in "airplane mode" and then rebooting it; that sometimes helps. If it's doing something like checking for emails in the background it starts to judder badly.

if core player has a buffer size setting try setting it higher try setting it to 32864kb. or do what i do and use TCPMP for videos. it has that setting and it works great for all vids. oh and its free! search the forums for TCPMP if core player ends up not working for you.

I've found that CP benches don't mean Sh*t, I can get 175% in a bench but play it back normally and it still drops frames

Yeah, the benchmark obviously displays average frame-rate; what you need to know is the time taken to render the single slowest, most complicated frame.

If I choose DirectDraw my device.exe locks up. I have had to stick to GDI. I only drop 1 frame every 300 to 500

That is probably because you are not using the other settings correctly: YUY2 overlays, etc.

Selecting DirectDraw alone will make CorePlayer crash. You need to make sure you set all the other settings in the 1st post too and then it runs much smoother than GDI.

Poor video Playback.

Hi,
It seems to me that the HTC HD suffers from poor video playback among other performance problems, I didn't know devices this new were affected by this problem as I remember there was a Class Action website concerning some affected devices with poor playback.
I have even used this program which supposedly will encode videos to play well on the HD : http://forum.xda-developers.com/showthread.php?t=467112
Used the factory settings, and video glitched and froze in many spots, also went out of sync many times. Used default bit rate settings. Tried playing in both "Album" and Windows Media Player, same problems
Seeing how the HD plays this video I wouldn't even consider trying Coreplayer with Divx/Xvid.
Is there any drivers/fixes to improve video playback or upgrades in certain ROM/Firmware releases?
Thanks.

that is over all a difficult question, because it consists of many aspects.
first of all, that program uses high bitrates and if it converts to wmv, a poor codec. if you take regular 624 x 352 16:9 xvid files, performance is higher. that's the 2nd thing: you said, after seeing album and wmp perform this bad, you wouldn't even give tcpmp or coreplayer a chance. but actually, they do much better in general, after all, you have way more options to optimize playback depending on bitrate and resolution. you could set the buffering and use options like "override avi framrate based on audio", "prefer lookup tables over arithmetic" and "prefer less buffering over smooth video" to get it to work to your demands.
and of course there are many ways to tweak the performance even further: you can of course try different radio roms and corresponding rilphone versions, different roms (which come with different tweaks cooked in by the respective chefs), or even go further and play around with different drivers, like neo2007's driver pack, or use gfxboost, winmospeed, hdtweak...
i have absolutely no problem playing regular xvid files (as stated above: 624 x 352 xvid, overall bitrate just above 1000kbit/s, 175MB per 22 minutes) absolutely smoothly on my blackstone with audio synced at all points. and that way, i don't even need to convert the videos.
as you can see, it is not done by a single tweak to make them run, maybe you need to switch the codec, the player, the rom and make a lot of settings, but if you want proper video playback, it shouldn't be too much for the result you get. also have a look at the codec info i posted, they are very commonly used.

Hi,
I've tried NEO's driver pack, doesn't seem to help, it was a cab file that I installed, I think it said that those drivers dont improve video playback but are more for improving touchflo and 3d performance? i may be wrong.
That program encoded to AVC I don't think it used WMV (or is it pretty much the same codec?).
Just wondering how do Radio ROMS affect the video playback? I thought the radio rom is for the Phone/GPRS operation?
Also how do tweaks on ROMS affect the playback, I thought it was limited to that the processor simply cannot do the work to make the video play smooth as there doesn't seem to be any dedicated graphics/video chip? Do chefs do tweaks on how the OS uses it's memory? Just wondering what sort of tweaks they are but this might not be a simple answer.
I'm surprised how xvid @ 1000k plays well on your blackstone, hmm. Seems my playback method on coreplayer is "QTV" is that the video accelerator on the Qualcomm Chipset ?
xvid video at 830k at 608 x 400 plays borderline on my blackstone on coreplayer, when Panning on movies it jerks. 1778 frames played, dropped 551.
I would have thought preffer less buffering over smooth video would make the video rougher? going to the description of that option.
I tried ticking those options you suggested, they only slightly improve the playback, however i tried this suggestion from another thread :
"For touch HD, just tick "Disable AVC Deblocking" at advanced tab, "soft drop tolerance" to 0.3 sec, and let other settings defaults. Enjoy your hardware-like video player."
Seems to help the most out of any suggestion but still jerks sometimes.
I'll look into winmospeed to see if it can do anything to speed up my video playback and my device, but not sure how the Qaulcomm CPU copes with overclocking, especially stability and reliability.
What is a safe speed to run at?

which driver pack to use depends on which rom you are using, some roms already come with a driver pack and installing another one makes the device slower rather than faster. the drivers, as you correctly pointed out, generally affect the 3d performance, however, it is about hardware acceleration and some players use hardware acceleration, which should be the same chip, the gpu.
you might be right, the program might encode in avc, just had a brief look at the screenshot, and as you mentioned windows media player, which supports almost no codecs i just assumed, it would go for wmv. as already pointed out, i don't encode my files for the phone. too much work for watching once. instead of re-encoding, i could watch them on the pc instead.
radio roms don't affect video playback directly. they do more than just handling phone calls and wireless communications though, radios are the bridge between the winmo OS and the hardware, so also bluetooth, wi-fi, camera, sound and many more things are influenced. but most of all i mentioned it, because i went through a lot of roms recently, beginning with the latest orange uk stock rom and on every single one of them i experienced an improvement in performance, when i used the newest radio 1.17.25.09 with them, with corresponding rilphone. many cooked roms have specific rilphone versions cooked in, and the radio should match for the entire device to work properly.
as i have never cooked a rom, i certainly can't tell you any of the chefs' secrets, but i assume it takes a lot of work and tweaking, to make new builds and sense versions run properly on this rather slow device. many chefs point out to have compressed a lot of graphic files and optimized cache sizes, pagepool...
some of these tweaks can also be altered with hdtweak.
at the moment i use tcpmp cooked into the energy rom and i believe avc deblocking was ticked by default, or else i would have mentioned it, but i also read before, that it should stay ticked on for better performance.
for winmospeed i mostly set it to level 32 or 33 while playing 3d hd2 games, which are generally very slow on the blackstone. having it permanently set to level 33 causes the phone to freeze sometimes, so that speed seems to be the borderline.
if nothing else helps (and that included trying other roms), you could also disable sense, when you watch videos, if it is so important to you. when watching tv shows or movies, you are not using sense for a rather long time anyway and it really hogs ram and cpu.

agreed.. level 33 = 633mhz is borderline..
a hell of a lot faster than normal 528mhz!
set to level 33 does make the device crash sometimes but not often, i personaly recomend level 33 regardless..
1/10 times it will crash, in my experience its on device first boot after customisation. soft reset and all is ok.
it could be my rom though haha - i joke!

overclocking is completely safe dude, already read up on this before i even tried it when it was released.. so to save you reading, just download it, its worth it
