Sorry, you are right, I meant ND22 according to your review.
The ND22 looks superior to AD02 from your review. But I couldn't guess why.
Is it the GPU used in ND or the software maturity of its drivers because it was there for longer time than AD?
for Ubuntu+vlc+1080p, which one is smoother play back and why?
I mean if it is a vaapi library issue that puts the AD back, would there be a hope for it to beat ND in GPU tasks performance later?

For me, the overriding issue for any 1080p is that the NVidia proprietary driver with VDPAU seems to in practice be more maturely supported at this time than the AMD proprietary driver with XVBA. Note that I did NOT test with vlc, I'm using xbmc for 1080p playback.
The CPU in the ND22 is significantly faster, but also has higher power draw and heat - for an HTPC, probably I would rather have the lower heat allowing a quieter fan, if all other things were equal, personally.
If you get everything configured right and all the drivers and libraries happy with each other, they BOTH will play MOST 1080p smoothly enough. But, (1) the driver / library maturity issue is more painful still on AMD; (2) _some_ 1080p files play much better on the ND22; and (3) I did run into more sound and system stability issues on the AD02.
I don't know the history of the difference between the NVidia and AMD drivers and library support and such, I just know that the end result is that there is WAY more opportunity for frustration with the AMD graphics for _right now_. My "executive summary" is that in general the ND22 "just works" and the AD02 "can be made to work almost as well after you tear your hair out".
That doesn't mean the ND22 is a better choice for all users - the AD02 is cheaper, and uses less power (=heat). And it looks better. And is apparently fine under some other operating systems, I _only_ use Linux.
As far as the future - sure, the fglrx+xvba+vaapi might support uvd3 and bake cookies and run rings around NVidia - but - I wouldn't actually make any decisions based on what MIGHT happen...

any solutions on the 24p problem right now? 24p + vsync and xbmc still stutters =(
I tested yesterday Ubuntu minimal x64 + Kernel 3.0 and catalyst 11.7 + newest xvba and xbmc 11pre from lars.
60hz looks fine so far, even if vsync is on. Performance is good too. Load slightly better than in older versions, 15-25% @ 1080p.

Somebody can give the link to a ready image of system? For testing.
I can't build full-function xbmc yet (: Something wrong with vaapi........

Thanx, sraue. I try it.
But I hope to see real image xbmc, builded from PPA. 2 weeks I do not sleep all OP from topic starter and others => nothing...
deb from lars looks fine, but any movie crushed my builds.
Now i finished with another question: crush-log stops on "ERROR: Initialize - pcm_open_lconf, alsa error: -2.."
New installation = new problems I like it!

Is it possible to add TV support to OpenElec, too?

OpenELEC has initial TV support in our normal images, also there are experimental images with XBMC's PVR branch.

Toesher, Thank you, very thorough answer.
The AD02 hardware is built to run HD videos, there must be something wrong I'm doing.
Today I'll try:
- Install Ubuntu.
- Install fglrx driver.
- Install VAAPI stuff (xvba and libva..)
- Compile ffmpeg with vaapi enabled.
- Compile VLC with VAAPI enabled.
- Compile MPlayer with VAAPI enabled instead of VLC.
Before that, I'll try the live XBMC image from Nemek to play the killa-sample.
If it runs smooth, then I'm definitly doing something wrong.
Get back to you with the results.
Thanks Robotica for this awesome topic.
I have done all the options above, actually Toesher was right, it is very simple to install.
Using Toesher method, or option 1,2,3 above. All gave same results.
The ZBOX AD02 with Linux sucks with "killa-sample.mkv", other 1080p videos run smoothly with tolerable tearing.
With VLC the both cores takes 50%.
With Mplayer both cores takes 20%
Both XBMC, VLC, MPlayer all have same playback performance mentioned above.
The driver really need more developement....
Thank you all for the great topic and advises.

1080p + 60Hz + vsync + resample audio = sweet. I have shit loads of music videos and the constant video mode changing gets really annoying. To be honest at this point I really don't see any need to be concerned with 24hz. Even if they fix it I doubt I will use it...
