[mythtv-users] XvMC not quite working (undefined symbol: XvMCCreateContext ?)

I'm running amd64 3700+ on Ubuntu 6.10 with 1 GB ram and a GeForce
6100 chipset using DVI out to a 480p projector.  I thought this would
be enough to do HD w/o xvmc but it drops a few frames each second,
Xorg is using more CPU than mythfrontend (70/30 usually).  So I
thought I would try XvMC.  What is interesting is the line:

/usr/lib/libXvMC.so.1: undefined symbol: XvMCCreateContext

this sounds like my XvMC lib is bad?  If so, any tips on correcting
this?  I would like to try the latest binary nvidia driver, but it
always fails to build a kernel module.  So I am using the latest
ubuntu package (8776 I think).

Thanks
