I have AMD Athlon XP 1700+ + DXR3 card and experience similar problems
(I use em8300-0.12.0 and dxr3:noprebuf as the manual says). All my
DVD, MPEG1, SVCD files lose a/v sync after a while, especially after
seek.

What's actually funny is that _some_ of my AVIs maintain the A/V sync
throughout the whole movie, no matter how hard I try to break it with
seeking, pausing etc. And some of them just work as all the MPEGs
actually decoded on dxr3 card. I'll try to find good and bad behaving
files and upload their 5M pieces to /incoming.
