I have made a fresh new installof ubuntu jaunty (i wonna hdmi audio :P)
i have installed svn build 18324

Changed resoluction manually to 1080p (tried both 50Hz and 60Hz).

Both in menu and video playback of 720p mkv h264 i got only 18 fps.

Athlon X2 5200+
Asus M3N78-em nvidia 8300 chipset
2 GB ram

audio isn't working atm (i'll try to fix it later)

This HW on Vista can handle 1080p mkv h264 whitout frame drop.

Tried both gnome and xfce with same results
Any idea?

Um, try xbmc-vdpau branch to get nvidia's acceleration working:

Yeah I think you need VDPAU with that CPU.Unfortunately AMDs are not optimal for 1080p playback without GPU accelleration.

Uhm nope, i have also tried on debian with mplayer i can handle 1080p with 70% of cpu... with xbmc i have a lot of cpu free when playing isn't a cpu problem.

I think could be a xserver (jaunty use 1.6) and nvidia driver 3d issue.

Well..My previous setup only had a 7100GS video card and I had a 2.53GHz Core2Duo and it could play 1080p without problems even killa sample without dropped frames.

Try the XBMC live and see how it goes with that.You can run it off the CD.

Tryed now with xbmc live, near 22 fps...but with cpu0 at 100% and cpu2 at 40% this sound strange.

Your problem sounds kinda like the problem in this thread:
http://xbmc.org/forum/showthread.php?t=46783

We are trying to figure out if it is VDPAU specific or not. Try the sequence in post 15 of that thread with your normal setup and let us know the result. Also take a look at my last post there for another thing to look at.

I readed all the thread u linked, seem i have the same throuble...
I'm building my own xbmc svn package on debian, i wonna see if is a ubuntu Xorg fault (1.4.2 of debian is very faster than 1.6.0 ubuntu one)

If you follow the sequence in post 15 of that thread, does the problem go away?

Nope the problem is always here.

Pulsaudio -k not yet tested.

finished now to compile through ssh on my debian lenny with 2.6.28 kernel (same htpc), compiling now vdpau version, i'll try both version and i'll write here results, and i'll compare with ubuntu xbmc svn.

Time to go home now.

done last test.
linuxport svn on debian lenny played at 22 fps but i don't know why it is using only 1 core 100% cpu1 20% cpu2
vdpau snv on debian lenny played near 18 fps with cpu at 10%

is not a pulseaudio issue on debian i don't have pulse installed.

Sorry to be repetitive - but did you try the sequence from post 15 of the thread I mentioned earlier once you installed VDPAU?

Yes already tested, nothing changed in both version.

To test this bug i must start with resolution set to auto ok.
I must start xbmc in fs or in window mode?
If i start in fs mode i have no change. I'm trying now with window mode.

shassino

I can confirm U i have the same issue, if i start i window mode (auto) and manually set to 1080p fs. I can run Iron man 1080p well with vdpau with only 11 frame dropped on the movie start:).

I can also confirm that this affect both vdpau and linuxport.
