[mythtv] mythtv-vid branch needs testing

[Asher]

The main thing I have is the lack of overscan with the opengl
renderer.  Some of the videos have the vbi info at the top and it is
pretty distracting to have it there.

I also noticed a lot of prebuffer pauses when playing back HD content.
 I set it to just use regular XvMC with (I believe) the same settings
that I use for trunk without problem.

I don't have my logs accessible right now but there were messages in
them stating something along the lines of "deinterlacer 'xxxxx' not
active'  It didn't matter which deinterlacer I chose, even none it
would say that.

All that said, the video quality does look better for SD shows, and I
love the full sized OSD displays
