It was segfaulting as soon as I started.

Sorry, I can't provide a capture, I simply downloaded the package, updated the source to a new revision and it started right away.

BTW, I have completed ported VDPAU support to 0.21-fixes..
Available there:
http://www.avenard.org/files/mythtv-vdpau/
along with Ubuntu packages ...

Works great for me at least
