That was my understanding as well. So I will retry and check the logs again.
I'm away from the box right now, but from what I remember it tried to open
some kind of lib*nvidia*.so, which I obviously don't have.

Well, yes and no. I never tried it myself, but AFAIK there are actually two
bridges, VDPAU to VAAPI, and VAAPI to XvBA. Bottom line is there is some
kind of VDPAU support, but since I was never really happy with the Catalyst
driver (bulky, ugly tearing) I have long since exclusively used the open
source driver which gives excellent Xv performance (but unfortunately poor
OpenGL rates - see also http://code.mythtv.org/trac/ticket/9216).
