Well using anything newer than the 7676 nVidia drivers will result in  
the v-sync problem, and I haven't got up the nerve to use any version  
of MythTV that lets me turn that off with a checkbox (guess I'm  
waiting for a "release", soon now it seems).

I'm pretty certain that others have made XvMC work with 7676, albeit  
on 32-bit machines perhaps.

I think the error is a pretty generic one, seems to mean "something  
didn't work".

Thanks for the input.
