Hi William,

Thanks for replying.
I'm using Ubuntu. Installed bits using the Synaptic Package manager 
mainly. Some bits using apt-get.

I did read last night that the sources have to be built (if that's the 
correct terminology, I've never built a source in my life) to enable 
XvMC, but I assumed that the Ubuntu installs were ok. Maybe I was wrong?

My current best shot at fixing this was finding 
libXvMCNVIDIA.so.1.0.9746 in /usr/lib/
I tried putting /usr/lib/libXvMCNVIDIA.so.1.0.9746 into 
/etc/X11/XvMCConfig but it seemed to break things. The screen just goes 
blank for live TV and mythfrontend output seems to be constantly timing 
out or something.

I've switched the file back to read libXvMC.so.1 for now.
