Before I ask my question, my setup is as follows.

MythBuntu FE 9.10 w/ JYA's repo enabled
nVidia 9500GT w/ 512MB RAM
MythTV 0.22 with VDPAU successfully enabled (Advanced 2X with 1x Fallback)
nVidia drivers 195.30

MythBuntu BE 9.10 no JYA repo
MythTV 0.22 no VDPAU

I have a video file on my box that I know is 23.976 Hz rate.  mPlayer has
confirmed this is a 1920x1080 VC-1 23.976 clip.  I played the clip using
Internal and my TV is still showing 60Hz.  I know my TV does 24Hz because
I've seen blurays on my PS3 and the TV shows 24Hz.  I've checked the VIDEO
MODES screen under APPEARANCE.  My settings for "Separate Video Modes for
GUI and TV Playback" are set like this:

GUI:  1920x1080
Video Output:  1920x1080
Rate:  Any
Aspect:  Any

All the overides for specific video sizes are 0, 0 320x200 Any Default  (I
haven't changed them from their defaults).  What am I doing wrong?  I have
nothing special setup in my xorg.conf.  It's just a plain vanilla install of
MythBuntu except for the JYA repo.

Also, when playing through INTERNAL mythtv player, I would get what looks
like bits of video that weren't decoded right.  They are small miscolored
blocks that appear and disappear.  They aren't there all the time and they
aren't there in the mplayer playback of the clip.

Thanks for the help!!
