It's a 733MHz PIII, 256MB RAM, and the video is the on-board Intel
i815. Only attempting SD :-)

While watching video, there is no swapping or other disk activity,
so memory doesn't seem to be an issue. CPU usage is dominated by:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 2079 mythtv    15   0  284m 133m  30m S 66.4 53.6   6:00.31 mythfrontend
 1971 root      15   0  114m  46m  21m S  6.9 18.6   0:39.92 X

Xorg.0.log says, inter-alia

(II) Loading extension XVideo-MotionCompensation
 and
(**) I810(0): 7 XvMC Surfaces Requested.

but mythfrontend says this with -v playback:

2006-05-12 21:56:37.600 VideoOutputXv Error: XvMC output requested, but is not supported by display.
Xlib:  extension "XVideo-MotionCompensation" missing on display ":0.0".

Of course. The overall experience is not too bad, but on fast moving
program content (e.g. sport) there is definitely a jerkiness to the
display that was not apparent on my other frontend (Athlon XP2400 without XvMC)
