Bug Description
I'm running 10.04 lucid. depending on the file type, the bug acts differently. with mp4, the video will become unsync'd with the audio and will speed or freeze depending on how bad it gets. with mkv the audio will stop and come back seemingly at random with no effect on the video. its unaffected by video card or video card divers. and compiz has no effect on it either. I noticed my friends computer was doing the same when I ungraded him to 10.04 yesterday. he is running an ATI x1300 card (open drivers) and im running nvidia 8400 gst (closed drivers). And on top of that I have an Intel processor and he has a amd x64. So it seems to have absolutly nothing to do with hardware. I haven't tested any other video player yet, so it may have something to do with totem or gstreamer. there is no problem that I can hear with audio in general though, rhythmbox plays fine no problems. so it seems to limited to video files only for some reason....
This bug was not in 9.10, it just started after upgrading to 10.04. To reproduce all I have to do is play an mp4 or mkv file. the videos are in 720p if it helps any. this doesn't happen when playing avi files, though that may or may not be because they are SD.

Given the difference seen between HD (720p) and SD video, I suspect your CPUs are not powerful enough to show the HD videos smoothly.
Can you verify that hardware- accelerated direct rendering is enabled? - please provide the output of glxinfo |grep render on each system.
Also, on the NVIDIA 8400 GST if may be possible to enable VDPAU if it is not already enabled.
