I have Fedora 9 and an Asus P1-AH2 with an Nvidia 6150 onboard
graphics chip and 64-bit AMD CPU, so your mileage may vary, but how
about your /etc/X11/XvMCConfig file? Did you configure it per
http://www.mythtv.org/wiki/index.php/XvMC?
# ls -al /etc/X11/XvMCConfig
-rwxr-xr-x 1 root root 27 2008-08-04 12:55 /etc/X11/XvMCConfig
# more /etc/X11/XvMCConfig
libXvMCNVIDIA_dynamic.so.1
# find / -name libXvMCNVIDIA_dynamic.so.1
/usr/lib64/nvidia-graphics-173.14.12/libXvMCNVIDIA_dynamic.so.1
