[mythtv-users] XV doesn't seem to be working

[John Winkeler]

I am experiencing high X usage (90%+) when playing back live or recorded
as well as getting diverged audio/video when playing back HDTV.  This is
running on FC4 and using nvidia drivers from ATRPMS.
 
The XVINFO output below is common with either the 7676 or 7667 nvidia
driver enabled. I don't see any of the normal stuff like color_key,
etc., is XV actually working properly? Any good methods to tell?
 
Thanks,
JW
