Er, pretty embarrassing to write on a -dev list, but actually I didn't
recompile MythTV for this test. I simply turned on VDPAU in the settings and
tried to get some results. I would not think that recompiling MythTV changed
the dependency on some nvidia specific library, except that I probably
wouldn't even be able to even compile it without errors.

What I suspect is that the player, while using VDPAU, also tinkers with some
nvidia specific things. I meant to analyze the sources for more insight but
haven't got round to it yet. If my suspicion is correct, then the generic
VDPAU would be needed to be factored out somehow into s.th. which is
generically usable.

Has anyone perhaps ever tried the VDPAU to XvBA bridge from Splitted Desktop
with the Catalyst driver? That should show pretty much the same issues, and
maybe they're solved already?
