Well, I've had a few minutes to remove the vdpaustudio from the
playback filters and see how things looked with YUV output....  I used
the AVS calibration files for White / Black and Hue / Tint settings.
The Hue / Tint were dead on.  The White / Black were WAY off from
using RGB with the vdpaustudio filter.  I could not see any of the
black bars in the Black Level test pattern and had to really increase
the Brightness.  I also had to significantly increase the Contrast as

Video (HD and SD) seems OK but I'll need to watch something to see.
The Mythtv menu looks extremely washed out.

I think I need to play with this a bit more before I decide what is best.
