I have a 2.53Ghz Celeron in a Shuttle running FC3 (stock uptodate
kernel) and see similar behaviour. The image motion is not always
smooth and a few % of frames are skipped/dropped by xine or aren't
synced properly in the X/ivtv driver. It's most noticable on a smooth
panning shot. I thought it was due to cpufreq so I switched that off
with no improvement. I don't have any av sync issues.

I agree, it's 90% ok, maybe even 95% but I've never really achieved
100% even though my CPU is only ~40-50% busy. Are you recording off
the PVR350 at the same time that you're watching Xv?

I did wander if it was a memory bandwidth issue as I know that
Shuttles have relatively poor memory throughput but I can't really
believe that a recent P4 mobo with DDR400 RAM is unable to software
decode a DVD in realtime...

Latest ivtv and X driver.

If you've managed to get 100% smooth Xv playback, please can you list
your hardware and distro/kernel version? If I know that it's possible
to get 100% smooth divx/xvid/mp4/DVD playback, I'll keep trying other
things...

Cheers,
Wilf.
