mpeg2player is just not sufficiently optimized yet, and can't take
advantage of hardware acceleration like colourspace conversion (unless
you're feeling brave and you have a G400)
With the -ns option on mpeg2player, which deliberately breaks sync
between video & audio, it's a bit smoother. You should also try XFree86
3.9.18 which is remarkably stable (I'm not going back to 3.3.5) and a
damned sight faster. I get around 20fps (Devil's Advocate) on a 450MHz
Celeron with a TNT card. 3.3.5 was about 20% slower even with
write-combining on.
Paul.
