[Q] Xoom HD playback capability

There are a lot of MP4 video clips that I cannot get to play on Xoom smoothly but they play back really well on my HTC Desire.
On Xoom the video is laggy while the audio is audible. This happened to both 720p and 480p videos. I used both the default player and Moboplayer to ensure I am using the hardware acceleration.
Strangely on my Xoom the Moboplayer can soft-decode 480p MP4 with ffmpeg and playback without any problem. 720 is smoother but the decoding was too slow which resulted in A-V async.
Again, all those clips play really well on my HTC Desire. Tegra 2 should be able to handle them.
Anyone knows anything?

Please search the forum before asking questions. This has been asnswered.
The problem you're having is to do with the clips using high profile encoding.

There's lots more. All I can say is, learn to love Handbrake and be prepared to have your computer running all night every night if you ever want to watch HD movies on this thing.

I dont agree; I have transcoded 2 blue rays, hellboy and start trek 2009 in about an hour each, using my imac and handbreak
Oh, and download Vitalplayer from the market for the best hd video playback..

Yeah, well, I don't agree.
I converted 2 720p mkv 90 minute movies and a 40 minute 720p mkv TV show last night and it took 6 hours. This was done on an Intel Core 2 duo P750 2.26GHz
Not everyone has the same hardware. I suppose I could run out and buy an i5 or i7 for the sole purpose of encoding video for the XOOM.
Maybe Motorola can partner with a PC company. How about 20% off a new laptop when you buy a XOOM that way you will be able to take advantage of its HD video capability in 2 hours instead of six.

It all depends on your settings, and keep in mind that the imac is going to have similar hardware to your machine. The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware. Also, keep in mind that encoding is entirely processor bound and will do better the more cores you can throw at it.

Been there done that. There are no shortcuts. Good quality takes time or more cores. Or harness the GPU ie CUDA but that causes horrendous macroblocking in bright scenes.
No matter how you sugar coat it, re-encoding video is a time consuming pain in the ass for most people.
I also seem to remember there are multiple versions of the imac, with variable hardware specs, from dual core up to quad core 3.6GHz - so your claim of similar hardware seems unlikely.

Suggest using 800 max width for substantially faster encode speed and smaller size. Quality diff is negligible on a 10".
If using 2-pass, switch to 1-pass for both faster encode time AND better quality.
Unfortunately, HB doesn't provide x264's speed presets. You can gain additional speed (at cost of some nominal size increase) with the faster presets. Hmm, I should update my HB script to allow "downloadables" as input.
>The recommendation is to set max width to 1280, set B Frames to 0, turn off CABAC, 8x8 Transform, and Weighted P frames. If you do that, you'll find fairly consistent encoding times even with older hardware.
Encoding to baseline profile (what the above basically means) gains speed by disabling more advanced "compression" features. The trade-off is significant size increase, about +30% vs high profile.
Using a lower res allows more efficient settings. At 800 width, you can use main profile. Speed diff between main & baseline is insignificant. Speed gain for the lower res is substantial.

I appreciate that your trying to help, but those are the settings that I have been using already: 1280, set B Frames to 0, turn off CABAC, turn off 8x8 Transform, and turn off Weighted P frames....
and it is still taking well over 3 hours to re-encode a 1:30 movie.
I understand that lowering the resolution will decrease the encoding time, but I consider that a last resort compromise. In fact I would consider that basically a failure of the XOOM.
I have considered buying an i5 or i7, but I feel stupid buying a new laptop for the sole purpose of encoding for the XOOM, when I could just pick up my Galaxy Tab and just play these videos immediately. No encoding. Just copy them over and play.

I am quite sure those videos are not high profile. Their bitrates were around 2M, way below 20M.
And, as I said, I can even do soft-decode to play the 480ps which does not play well with hard-decoding.
480ps, man. 480ps. Stunning.

I don't really care about the encoding stage, I have an i7-950 which encodes a blu-ray in handbreak in well under an hour.
What I'd like to know, is are the codecs really this lacking, and will we see a solution?
I, like the OP have a HTC Desire and I could be devastated to find the XOOM can't handle the videos my Desire can.
Does it natively support mkv? I like to watch TV episodes in mkv like the 86MB Big Bang Theory episodes.
All my non-TV stuff I rip myself so I'm not concerned. Other than the DRM wmv I buy. Which play back fine on my galaxy tab.

Most TV shows that are 720p mkv, and are privately enoded, and downloaded, average about 1.2 GB and will and not play. Support for MKV as a container isn't a problem, its the profile of the h264 video in the container that is the problem.
If the Video that you like to watch is only 86MB, that doesn't sound like high profile 720p. So it might play, only way to know is to try or download mediaInfo and check its properties.
Good to hear that the i7 that you have can do a blu-ray in an hour. That sounds like what I should do eventually. Wonder if an i5 will do as well. I've heard that the i7, though it has 4 physical cores, is seen as 8 due to multithreading, wheras the i5 is limited to 4.
I watched two re-encoded episodes of fringe last night, and the Video on the XOOM is really amazing. It actually is almost worth the wait.

They're not 720, but they're nice enough on my Galaxy Tab. They are High Profile @ L4.0 though which I'v heard a lot of bad-mouthing about on the forum lately. I'm no expert on media codecs and frankly couldn't care as long as theyre watchable. I'd love to know I could rip my Blu-Rays at 720p and watch them on the XOOM comfortably though.

What you are posting is interesting. Its high profile, but low bit rate. Some of the early claims for the Tegra 2, which is used in the XOOM, said it actually could play high profile but only at a low bit rate, but I haven't heard it confirmed. I suspect this video will not play, but later on I will try encoding a video in a simliar manner to yours and see what happens.

Great, if you like I can dropbox the file I have and PM you the link for testing. These files playback flawlessly using the Galaxy Tab with every single player software I have tried, whether hardware or software decoding. FOr them not to play on the XOOM would be a killer.

Got your file. Sorry, it plays but with no sound. I tried RockPlayer and Moboplayer and the System Player and all play the same - silent.
The Video is actually pretty good. Smooth and very acceptable. So I guess it can technically play high profile, very low bitrate files - just not with sound. Have to Play around some more and see if I can learn anything else that might get this to play correctly or figure out what the problem is.
Edit: Actually, this is a Divx encoded file, not h264, so that is why it plays. So I am a little surprised about the lack of audio. And its only mp3 audio!!! This is really amazing. I can't believe the XOOM isn't playing this correctly. Has to be a way.
Update: Ok, success! It does play correctly in Rockplayer in software decoding mode. With sound. So it looks like you will have no problem.

Interesting, if somewhat concerning that it won't play this in the standard players or with hard-decoding even though it uses mp3 audio.
How about VPlayer Advanced? I find this plays most of my videos nicely on the Tab.

Probably just lack of Divx support in hardware. Thats not a big deal, even a single core CPU of lower power can easily decode low res, low bitrate Divx. I don't consider that a flaw at all. Software decoding video like this with the XOOM's dual core A9's is trivial. Results are fine. Just need an app like RockPlayer that does it. XVID files will probably not work in hardware either.
From Motorolas website:
PLAYABLE FORMATS
AAC, H.263, H.264, MP3, MPEG-4, ACC+ Enhanced, OGG, MIDI, AMR NB, AAC+

Yeh that's pretty fair I guess. How do you think it would manage if converted to MP4? I can do it on my 950 when I get home and send you it if you like? I'd not mind converting the whole lot if it played in the stock player.

Lagfree playing of .mkv 720p/1080p source

Hi folks,
Is there any posibility of a lagfree playing of those videos ?
It sucks watching Videos with less than 20fps...

3.1 is supposed to improve playback... just no idea if it will improve 720/1080p playback

I use Handbrake and imported these setting I found on the net.

That Google site is mine.
Converts all my 720p.mkv files perfectly, the only issue is the files are big, 2-4 GB, but the quality is outstanding. They even play on 'Movies' which darkens the navigation bar.

i was looking for something like this so many times before, but I never found a stable movie app. On my Samsung Galaxy S II however, it's no problem at all. And that's a freaking phone man! But it's no wonder the hole system is so fast. It makes my newly aquired Iconia looking really sluggish and outdated :-( I don't know if I gonna keep this tablet or gonna look my movies on a 4.3" screen...

I asked Acer customer support whether they're ever going to support additional formats and they replied that they won't ever add support for MKV and can't comment on the rest. So official support for MKV is out the window.

Mkv isn't a video format, it's a container. It's just that most mkv's don't contain only baseline h.264, which is the only supported video format currently. The most benefit would come from adding support for main or high profile h.264

I know, it still doesn't help at all if the video player application or framework don't support the container format. I personally love MKV, it's handy to slap in two different audio tracks and subtitles in English, Finnish and the hearing-impaired version, plus any metadata about the movie itself. No need to hassle with several files then.

Indeed. I tried transcoding a 1080p movie to 720p in constant quality mode, both in baseline and high profile modes, and while the quality was the same the high profile one used a lot less storage space. With storage space being rather scarse on mobile devices....
Well, we can only hope. But I don't know if the DSP is beefy enough to decode high profile or if it can be re-programmed to support it. Some DSPs are hardcoded and can't be used for anything other than what they already do when shipped. I don't know anything about Tegra 2 internals so I don't know what to expect.

Why ACER can't (won't) support them is beyond me! Even my Single Core 7" Samsung Galaxy TAB can play all 1080p videos I have thrown at it!
And here is the full spec of the Tegra 2 250 Link!

Is it maybe because of that, that I play these videos from my USB-HDD?

You can always copy one of them to the TAB and see if there is any change ( I doubt it)

Using a OLD 60gb usb hdd (literally 8 years old)
And it does not seem to matter - even with the low speed of an old external drive I have no issues playing video from it.
.Mkv -- Regardless of where it is stored is not going to work on the Iconia right now - i don't think there is anything anyone can do or change to fix that right now - the system will not?/can not? use the hardware decoder on mkv files - and software decoding, even for a low bit rate video file is always going to suck.
Hopefully 3.1 will improve our video performance - but I find it a very simple matter to just transcode a video file if the only source I have handy is mkv. Plenty of great and free tools that make the process pretty darn easy. I watch a lot of movies/TV on my a500 - and get a great experience as long as I don't throw .mkv files at it.

My understanding is tegra2 will support h.264 high profile up to 720p @ 20mbps, but only baseline profile for 1080p.
With regard to the container format vs video format thing, I'm under the impression that container format support can be added by an app - so even if Acer never support mkv in the default player, if they do add hardware high profile h.264, then other apps should be able to play an mkv that contains high profile h.264 with hardware acceleration.

From playing around with PRIMEE, mkv containers are split appropriately and if the video format is supported hardware decoding works. The problem is that there is no support for AC3 therefore majority of compatible MKVs will play very well but have no sound.
Unfortunately once software encoding is enabled we are back to the same stuttery playback issues.
I personally don't believe it's Acers' job to add playback compatibility, I personally believe it should be built into Honeycomb as a baseline. Honeycomb is a tablet OS and as such should be expected to play popular video and audio. codecs. Saying that, if manufacturers did add additional codec support it would be a solid competitive edge.

Use mobo player.

Have you read any of the thread, running moboplayer doesn't help, as I mentioned above as soon as you enable software decoding HD MKVs start to get choppy.

Ah, that's good to know, so with a baseline h.264 payload an MKV will play fine on stock?
I think it probably IS Acer's job to add codec support, frankly. At the end of the day we're talking about hardware acceleration, and Android provides the software framework for that to work, and it's up to the hardware vendor to make it work with their specific hardware.
Frankly I think Nvidia should be doing it though - it'd do wonders for Tegra 2 sales if they offered up code to support hardware acceleration for their platform on Android.

I guess you didn't really do your research on video playback on Honeycomb tablets, did you?
You can not blame Acer for poor HD playback when, frankly, this is a Google/nVidia issue. Currently no 10" Honeycomb tablet can playback high profile encoded HD vides--smoothly, if at all--without reconverting said movies.
There may or may not be a *real* fix in the future (quad core Tegras are right around the corner, so...), only time will tell.

I bought an ACER device so I'll blame them! Problem here is that the Tegra 2 chip is capable to decode and encode the formats at 1080p without problems! The fact that Google still hasn't taken advantage of this feature doesn't mean that ACER couldn't!! To back my words here is an example:
Samsung! The Galaxy S and Galaxy TAB (7") they have much superior video codec support! I'm playing 1080p movies just perfectly on the Galaxy TAB. Samsung have invested in codec support and optimized it for the platform (both Hardware and Software) The Hummingbird CPU is Single Core! So why can't ACER do it? Maybe because they never did something like this before? Maybe because the have done only the hardware till now and they don't have the programmers that can pull this of? Ones the managers at ACER understand that selling thees devices without enhancing the base that Google provides won't cut it, I think we will have a very good device (not that it isn't good now but...)

So does the Samsung 10.1 play 1080p videos smoothly?
From what I've been reading.. no. Frankly, watching a 1080p on a 10" tablet is pointless (which is what I'm assuming you're crying about). If 720p isn't "good enough" on a 10" tablet, well, then, time to buy a 17" laptop.

Poor Video Playback

So, bought the Gtab on Friday, got a 32gb unlocked (Sweet). So, here is the problem that appears to be happening to almost everyone.
My video playback is Horrible, I've tried multiple codex's, and different Resolutions.
The videos so far i've tried.
3,343 Kbps 1280x720 at 29.970 fps, AVC ([email protected]) (CABAC / 4 Ref Frames) .MP4 Container, Very Choppy.
1,390 Kbps 640x272 23.976 fps MPEG-4 Visual (Xvid) Advanced [email protected]) (BVOP2) .avi Container Very Choppy
5,000 Kbps 1280x720 29.970 fps, VC-1 (WMV3) ([email protected]) .wmv Container Plays Flawlessly
Everything but the .wmv will play flawlessly on my Vibrant. Actually .wmv's are the only thing that i have found that won't play on my Vibrant.
I will test more configurations, but so far i'm not pleased with the video playback on the galaxy tablet.
I've tried other video players off the market, Moboplayer, mVideoplayer, haven't tried RockPlayer yet, but i had it on my vibrant and I felt the playback was not as good. Maybe i'll try it on Honeycomb.
So, I guess list your experiences so far, and suggestions. I will update as I go and find things.

Vplayer works great for me

Unfortunately, the fact that Samsung kept their hands out of Honeycomb has a downside. As far as I know, the Tab supports no more video types than stock Honeycomb. Which results in almost no good support at all. I've come to deal with it and you can, too.
The majority of my videos (720p and 1080p mkv) are converted and compressed while maintaining the quality by using this setup:

I found that this morning and tried it, i Converted 3 different files, and tried different settings, and they all run like crap. I guess i will try some other settings on it.

Who thinks Sammy should use Exynos in the tab? Tegra does not seem to be very friendly with respect to playback. I find it tough to believe that Tab looks so sluggish compared to GS2.

Just download a different movie player app. MoboPlayer works great, and it's free.

Whats wrong with just converting everything to hi-def MP4 on your desktop/laptop and dumping on your tablet? I mean the iPad does it with great success and gives the user the impression that it can play every video format??
The tab is a 10" screen, just about any video format 720p and above (hell even some 480p) will look just as good as 1080p on your 40-50" tv screen....or am I missing something???

What program and settings do you use, then?

Ok, I just purchased the 10.1. I use it alot to play back mp4 and m4v videos that have been encoded by Handbrake. What I've noticed on the 10.1 is that while they look excellent, when panning, the video pans with a jerky motion and is not smooth.
Any suggestions? I've looked around the forum but have not found anything definite. I've encoded the video at 720p.

From what i've read and researched, Tegra 2 only supports H.264 with Mainline Profile, Meaning 3 Reference Frames and no B frames, i've encoded several 720p Videos that way at 5Mbps and they play flawlessly.
While researching, i came across someone that came up with a Profile on Handbrake. That is what I've been using to encode my videos and so far, everything works great.
I will continue to do more Research.

Just a fyi, it does support High Profile, but with a max of 4 reference frames and 3 B frames.

It also includes presets for High and Baseline.

As I understand it, Tegra 2 should playback up to High Profile 720p and Main Profile 1080p. However, with limitation on Honeycomb and/or lack of driver release by Nvidia, current crop of HC tablets do not playback anything above Baseline Profile smoothly. Future updates by Google/Nvidia should fix this issue, but it looks like we may have to reencode High/Main profile media for the time being.

Even he says it, Tegra 2 currently doesn't support anything above Baseprofile because of driver limitations
But that thread is a Very good reference on how to encode video using handbrake, for Tegra 2 Devices.

He wrote that before the 3.1 update. He should really take that out.

I've only converted mkv files, but for 720p ones I use 1280 max output width, 20 video quality, live video type, high h.264 profile, and veryfast encode speed. For 1080p I just change the profile from high to baseline. All of my videos (with the exception of Avatar.....Man that's a long movie) are cut by two thirds. I guess I should mention though that I have a Motorola Xoom til I can sell it and get a Tab
If that doesn't work, just contact the OP of that post. He's really good at giving prompt replies.

Thanks for the information guys, I really appreciate it!

I just got my tab today and I am bitterly disappointed in how poor it is in terms of formts supported. Non of my avi or mkv files play (and when I use a 3rd party app they lag like crazy).

No, and besides what's the point? The screen is not even 1080p. You can try Moboplayer and see what happens. Best advice is to recode the file down to 720p mp4. Try Handbrake or Freemake.

I dont have the tablet yet but I'm going to buy and doing some research now,
how if we dont convert the file format ? is it possible to watch or is it laggy?
does the sound and the screen match?

Why would you do that?
The screen resolution is not even 1080 pixel height.
Don't you know that?
It's a waste of resources.
Try to get 720p instead.

Let me know what your research shows. I've been converting blu ray and mkv into 720p mp4 using DVD catalyst 4, real simple setup. From what I found out, mkv files do not work on any tablets because mkv is a container. If you convert it to mp4 then any tablet can handle it, including my phone galaxy s captivate . Takes me an average of 3-4 minutes per TV show and 10-20 on a movie. I stopped encoding at 1080p because there was not much difference other than size of file.

they work but not with high profile settings. you need to reduce them.
you can google what high profile for mkv is.

The answers you are looking for: http://forum.xda-developers.com/showthread.php?t=1060825

mkv is not a format, its a container for H.264 format.
You should be asking "is it possible to play 1080p H.264 in the galaxy tab 10.1?"
The answer is yes BUT (and a BIG BUT) you can only do so if the H.264 file is encoded in the old H.264 baseline profile which nobody uses anymore.
Tegra 2s video accelerator is way to slow to play H.264 videos that are encoded in the popular Main/High profiles which everyone uses today. Yes its unfortunate but you have to recode all your videos to baseline profile if you want to watch on ANY tegra 2 based units.

The tab, along with every other Honeycomb 3.1, tegra 2 device plays H.264 high profile 720p and main profile 1080p video just fine.
Although given the screen resolution, playing back 1080p video of any profile is pointless.

Correct it CAN play them back but at only very low bitrate and 1080p is not pointless since you can hookup to TV or monitor via HDMI

I did some testing on bitrates for the Teg2 at 720p HP here,
http://forum.xda-developers.com/showpost.php?p=15054949&postcount=250
it does OK at 6Mb/s, and chugs when bits hit 10Mb/s. 6Mb/s avg is about the ceiling for most 720p videos, so one can generalize that the Teg2, at HC3.1, will play a fair number of 720 H264 HP videos (in MP4 format). Ruminations are that HC3.2 will speed things up a bit further.
The clip, along with others, are here if anyone wants to try them:
http://www.mediafire.com/?depxt4zyvpwel

I've played with h.264 video on the Gtab, Use Baseline profile for best results. I've done some encoding in High Profile, and baseline, and compared screen captures, and you can't tell the difference, it has mostly to do with Compression, the higher your Profile (Ref Frames, B Frames, CABAC) the smaller your video file will be without suffering Quality lose. Just that higher profile requires more horsepower to decode, which Tegra 2 does not have.

Honeycomb only supports Tegra 2 CPUs. HC 3.2 brings support for Qualcomm CPUs. I could only wish this thing had the SGSII CPU.

Yeah, much as I like my Tab, I always feel like I'm taking a step back when I use it after using my SGS2...both in speed and display. I'd queue up in the pouring rain for a week to get a SAMOLED tablet.

Which explains why I am playing 720p24 high profile h.264 with no problems. Oh. Wait. No it doesn't.
Tegra 2 can handle high profile fine at 720p as long as you avoid wighted p frames. However the stock player does not. Enter diceplayer, built on the NDK and supporting all T2 decode capabilities. The stock player is totally borked.
1080p however is another problem. But you'll probably hit the fat32 4GB file size limit with those anyway before you encounter issues with high profile content. None of my 1080p MKVs will fit on the device anyway due to the fat32 limitation, so transcoding it pretty much a given. So I tend to go to 540p or even 480p just to save space. The screen is small, and while I can tell the diffeence between a clean 720p encode and 480p it doesn't bother me in this scenario. And if you drop down to 480p weighted p frames work again.
So, essentially Mr. Element, you don't what the hell you're talking about.

I can only support what ianken said. I can play 720p hig profile just fine with Diceplayer.
Here is a test clip to see on your own. http://www.multiupload.com/CJU6YB5JC3
It is in High 4.1 Format

just thought id let you know it does play 720p mkv files just fine (tested on my galaxy 7" with no skipping or slowness at all) assuming since it works on the 7" the 10" wouldnt have any issues with it.

I'm can play 720p high profile without any issues on Galaxy S Captivated. Gtab 10.1 and other HC tablets are using tegra2, that has some issues playing mkv high profile 720p. So far maker of diceplayer are the only one who have figured out how to make use of tegra2 to decode high profile 720p.

Play 1080p Video?

I've tried MX player, rock player and the default video player to playback my 1080p videos but they all still lag and play slowly. All videos are in mp4. Are there any apps out there that would be able to do this?
Cheers

try out dice player, and overclock, if ur tf is rooted, should be able to play smoothly. anyway I believe there are threads ard discussing this, please go do a search for them.

Dice player is the best by far IMO, even gets rid of the home and back buttons illuminating.
It plays mkv files and I have files over 3gb which also play without any problems.

not sure about 1080p that's going to be hit and miss especially if you have big file sizes.
I'm using revolver 3.2 at 1.3 and can confirm 720p playback with file sizes of 3 gig or so play perfectly with dice player.

This can play back 1080P files just fine....DEPENDING on the bitrate. It's a limitation of Tegra 2. If the bitrate is high, it will have problems. Just like 720P files with really high bitrates have the same limitations.
Honestly, why does it matter? If you're outputting through HDMI to watch things, then I can kinda understand, but the screen itself only supports 720P. Why bother with 1080P?

Just out of curiosity, does overclocking improve video playback?

Bitrate, uh?
How much is "really high"? 10mbps? 16mbps? and why the lower the resolution the higher the bitrate it can handle, if I got your post right?
Nah. I have a 1080p file, 16mbps. Plays well without overclock. I have another 1080p file, 10mbps, dosen't play well even at 1.6ghz. 720p file, still 10mbps, needs overclock (even 1.2ghz is enough). The difference between them? the kind of encoding. All this with Diceplayer, not the horrid Rockplayer, mind you.

Diceplayer works on most of my DSLR footage 1080 with 40-60datarate

If I remember correctly, movies encoded in High Profile will not play back well. Main Profile is the best this machine can handle. I believe it's a Tegra 2 limitation in general.

Let me comment on that:
LOL
Without OC, DICE player (and transformer itself) can only play Level3.1 content and it will slideshow on 99% of internet standard (scene) releases. If you think 'plays perfectly', then you're brain and eyesight damaged.
With OC, you can play play simple 720p content (think WebDL releases) with decent quality (though they will still drop frames in more complex scenes), but more complex releases (think blueray rips) will drop frames on most scenes and slideshow totally on more complex ones.
You would have to be really lucky to find a 1080p movie that will play. Many won't open at all, rest will be dropping frames constantly. When ASUS said that 3.1 update make 1080p playback possible, by playback they meant rendering first frame of the movie.

Dice player is the best
go for it

As mentioned on the other posts about HD playback, the hardware decode of 720p or 1080p H264 with AAC is currently broken in 3.2. Worked fine in 3.1, then got broke. Asus are aware of it and have promised a fix.
If you have such files (e.g. BBC iPlayer HD content) then no player will be able to play them back smoothly as software decode simply can't handle them. Only option is to either transcode or downgrade to HC3.1 to get hardware decode back.
Let's hope the fix is not far off now.

Well, there cannot possibly exist a difference between displaying 720p and 1080p on a 1280x800 screen, since all 1080p content would be scaled down to 720p. Where 1080p would actually matter is if you often connect to a big monitor or HDTV that is capable of 1080p, such as I do on a regular basis for when I want to watch movies without having to boot up my desktop computer. There is definitely a noticeable difference between 720p videos I've converted with Handbrake and the actual 1080p Blu ray movies, but it's not really a big deal for me.
My suggestion for those truly concerned about high quality 1080p playback would be to buy a netbook equipped with a Nvidia ION or comparable video chipset, as I have had no issues playing Blu ray from my own ION-equipped nettop.

yeah my MX player would lag like crazy. Dice is the way to go!
