I'm running myth on the "TVScreen" (on the left) which uses display :0.1.
I can only run myth using XvMC on this display; I will get error messages
stating that I can't create XvMC context on display :0.0

Without using XvMC, I can run myth on either or both (Also, I can run
XvMC on the TVScreen and non-XvMC on PCScreen simultaneously).

Whoops.  I should have followed the thread more carefully. :-)

Actually, I have been only running the XvMC version very shortly (2 days).
Until just now, I haven't tested it much other than running LiveTV
for most of the day and then last night watching a pre-recorded show.
Everything looked great.

But Speak of the devil, I just found problems with my setup when I try
to switch modes (LiveTV -> Watching or vice-versa) in the same session.
I get those pesky "can't create XvMC context" errors and things go crash.
I can use one mode at a time, exit myth, then startup myth and everything
works OK.  But this is not acceptable so I am going back to non-XvMC :-(

FYI, I have been noticing mplayer use XvMC without error for 2 months now.
