XvMC was b0rked awhile for me, I think it was an update Nvida pushed out.
Don't know if they ever fixed it.

It's my impression that VDPAU is the "next big thing" and being actively
developed.

By that time, I was starting to venture into HD land.  Circuit City was
selling HDTV PCI/PCIe cards for about $40 at the time, since they were going
out of buisness (Hauppage 1600's)

And my original backend went belly up.  So, it was about time that I
upgraded and re-purposed some hardware.

Never looked back.
