Thank you very much for your details, it's great you're trying to
help.  The libraries seem to be set up just like yours:

boron ~]$ ls -l `cat /etc/X11/XvMCConfig`
lrwxrwxrwx 1 root root 25 Sep 12 19:29
/usr/lib/libXvMCNVIDIA_dynamic.so.1 ->  libXvMCNVIDIA.so.1.0.8774
boron ~]$ ls -l /usr/lib/libXvMCNVIDIA.so.1.0.8774
-rwxr-xr-x 1 root root 170732 Sep 12 19:29 /usr/lib/libXvMCNVIDIA.so.1.0.8774

Using xdpyinfo for the first time here.  It gives me a lot of output,
hopefully this is all that is useful:
boron ~]$ xdpyinfo | grep XVideo
    XVideo
    XVideo-MotionCompensation

xorg.conf is using nvidia:
boron ~]$ grep nvidia /etc/X11/xorg.conf
        Driver      "nvidia"

I did see many errors when viewing HD whith XvMC.  I've reported them
in my first post so I won't repeat them, but they aren't very
intuitive.  Checking again however, I see that there are some at the
begining of LiveTV that I left out, so here they are:

and the rest is filled with prebuffering pauses and mpegvideo_xvmc errors

I really appreciate your help and the details that you provided.
Certainly discovering what isn't causing the problem is valuable in
determining the root cause of this.

Cheers,
