D'oh, I thought I could lay my XvMC issues to rest.

So the following is what I'm getting when I try to use XvMC to watch
NBC's "The Office" in HD.  I've got a Chaintec 7nif2 uATX
motherboard (nForce2).  It has integrated video, but I'm using a
discrete AGP geForce 6200 video card.  Athlon XP 2500, 2x512 MB RAM,
Gentoo Linux kernel 2.6.18-gentoo-r6, nvidia drivers 1.0.9746.

I've been through all the tips and tricks on the Myth wiki's XvMC
page.

Thanks,
Matt
