This should be more than sufficient. I have a similar system and it
works fine. Make sure your settings.pro includes -mcpu=pentium4 (not
pentiumpro), as this seems to make an enormous difference.
What video sync method is being used (from 'mythfrontend --verbose
playback')? OpenGL or RTC should be fine; sleep with busy-wait consumes
a bit more CPU.
If you're using nVidia's nvagp module, try using agpgart (and vice versa).
Also try 'renice -2 <pid-of-mythfrontend>' and see if that makes a
difference.
Make sure no CPU hog is running on the system. 'top' and 'gkrellm' are
your friends.
