Ok, I'm about to fold myself into a little ball and start crying ...
To continue my XvMC saga, and to make sure that it wasn't the rpm's, I
downloaded the latest source from svn and compiled myth, making sure
the --enable-xvmc was set. After a successful compile and install, I
fired up mythbackend and mythfrontend again. Unfortunately, besides a
spiffy-looking new interface, I got the same behaviour as before:
Without XvMC enabled, myth plays back PVR-150 content perfectly, but
content from the pcHDTV is choppy and unwatchable (though I
occasionally get a beautiful still frame from an HDTV show :) ). With
XvMC enabled, I get nothing but blank screen from both tuners, and I
have to kill mythfrontend to exit.
Just for fun, I ran -v playback into a log, and here's what I got (using XvMC):

So, as far as I can figure out, myth is using XvMC, and isn't
reporting any problems about it. When I look at my Xorg.0.log, I see
that all of the XvMC stuff is loading correctly. So, this should be
working perfectly, but it isn't ...
What am I missing here?
