[mythtv] Latest CVS XvMC - Nvidia Nforce2 IGP Live TV hangs

[Jeremy Garff]

Has anyone else seen this problem where watching recordings with XvMC
enabled is fine, but watching live TV results in artifacts and hangs
immediately after going to LiveTV?

I'm currently running the latest Nvidia drivers (6629), and the stream is
being sent to a remote client over the network (100Mb).  The linux kernel
is 2.6.9-ac12.  The CPU is a 2000XP and the compile options include OpenGL
XvMCNVIDIA and pentiumpro.

Previously 0.16 worked just fine with the exact same setup.

Thanks,

Jeremy
