No luck.  I tried setting both X and the GUI setup in myth to 800x600
and it's still slow playing HD.  Not stuttering, just slower than real
time.  I didn't mention before, but I'm using pretty much a straight
following of Jarod's guide with FC4, 2.6.14, on a P4 2.8.

I'm so close to having beautiful HD playback, can anybody suggest things to try?
