I'm currently fighting with the latest stable driver, but as was
mentioned in http://www.mythtv.org/wiki/XvMC#NVIDIA_2, there has been a
bug present in the nvidia drivers that require nvagp to be disabled. 
With newer drivers, if nvagp is enabled, XVMC stops working.

The last properly functioning driver for this feature was 100.14.11... :(
