Paul,

Yes, I wouldve thought that I wouldve seen some drop in CPU usage if 
XvMC is working, and I see no drop....it stays steadily ~98-100% 
whenever I watch anything from my pcHDTV3k card in Myth, Live TV or 
recorded shows....but if I watch TV thru xine, or any .nuv files 
captured on the card thru xine, and use the -V xvmc switch with xine, I 
see a drop to down around 58%, not a HUGE loss, but enough my uneducated 
mind could hope that it would be playable thru Myth that way 
then....thanks for the info about the Epia ad XvMC/B&W issues....now I 
know I can stop looking for it each time lol....anyone else have any 
tips for ensuring XvMC is working in Myth?  Just to add to the above, 
this is running MythTV from Atrpms, I believe its the 0.16.20 version in 
Axels repository (built 11/12/04 it says), and all needed nvidia drivers 
and kernel modules for 6629, the most recent version.
