Hi,

I've been using XBMC with ION based HTPC(Fiono330) on Ubuntu9.04. But the HDD was crushed in this week so I reinstalled OS and XBMC to a new HDD and then almost finished the installation.

But I've noticed that when playing some H.264 movies, XBMC can not play it correctly, it seems so many dropping frames and sound. Also FPS seems unstable and sometimes XBMC died. With my previous XBMC installed on Ubuntu9.04, there were no problem with playing those movies. I just presume this could be Nvidia driver issue, but could not figure out how to fix.

OS: Ubuntu 10.10 desktop 64bit(2.6.35-28-generic)
XBMC: 10.1
Nvidia Driver: nvidia-185-libvdpau (260.19.06-0ubuntu1)

Debug Log
In this log, the movie played first had no problem with playback. But the second and the third movie had the problem.


I'd really appreciate your help.

Kyouhei

try reverting to a 195 driver

try reverting to a 195 driver

Please can you explain how to revert to a 195 driver step by step...?
I'm very noobie...!!!! Tanks

Tried to install 195 driver but couldn't install successfully. Does Nvidia Vdpau Team PPA support Marverick?

However, I also had a problem with playing DTS sound over HDMI. I've found this thread and removed pulseaudio. After that, I have no problem on playing H.264 movie with 185 driver, I'm not sure why though.

Ah I noticed that the problem was not totally fixed with H.264 movies. When scanning the library background, sound would stop. And the sound only work with fullscreen mode with those H.264 movies. So I guess removing pluseaudio is not the best way to fix. I would try to install 195 driver again.

I was running 10.1 on one of my systems with Ubuntu 10.10 and it worked fine, now running Pre-11. Is there a reason you did a full Ubuntu install instead of a minimal install? Do you really need the Ubuntu desktop installed?

If not here is an outline of what I did to get 10.10 to play nice in my setup.

WheresWaldo,

Thank you for the guide. Yeah I don't really need full desktop. I will try to follow your instruction later today.
