[mythtv-users] XvMC Problem: Fedora 7, Nvidia 6200, Nvidia 100.14.19 drivers

[Mache Creeger]

I am running Fedora 7 (2.6.22.9-91.fc7) with the latest Myth standard 
release and an Nvidia 6200 with the 100.14.19 drivers. XvMC loads as 
reported by Xorg.0.log but when I run the standard myth program 
playback from mythfrontend I get an error. The mythfrontend setup is 
as follows:

Deinterlace playback is checked.
Box (2x framerate) is selected.
Preferred MPEG2 Decoder is Standard XvMC
Enable OpenGL vertical sync for timing is checked.
Enable realtime priority threads is selected
Use video as timebase is selected
Extra audio buffering is selected

Here is the relevant Xorg.0.log section

(II) Loading extension XVideo
(II) Loading extension XVideo-MotionCompensation
(II) Loading extension X-Resource
(II) LoadModule: "fbdevhw"

and here is the errors when I play video from mythfrontend

I have tried this with /etc/X11/XvMCConfig containing 
libXvMCNVIDIA_dynamic.so.1 as well as its actual location at 
/usr/lib/nvidia-graphics-100.14.19/libXvMCNVIDIA_dynamic.so.1. Both 
approaches have provided the same sad results.

Any ideas on how to proceed?
