[mythtv-users] X won't display on PVR-350 (black screen)

After fighting with this new PVR-350 running on FC3 for quite awhile, I'm
finally down to the last few problems.  I can watch LiveTV now, but X does not
seem to want to display on the TV-Out.  All I get is a black screen on the TV. 
It looks in the logs like X is starting, but it just is not displaying anything.
 I'll post the relevant info from the Xorg.0.log and xorg.conf files.  Any help
is appreciated...
