Well I'm guessing that however your version of MythTV was compiled, it
is linked against a vdpau library. In which case you may need to make
distclean, re-run configure and take it from there.

VDPAU is an API. Yes - NVidia wrote it but you can't do anything
nvidia specific. You're either working with the API or you're not.

Do you mean VAAPI to XvBA?
