There is information telling individuals to create a VDPAU profile
manually on the VDPAU wiki page:
http://mythtv.org/wiki/VDPAU#Display_Profiles. It is pretty easy to
setup the profile, it hardly seems worth scripting it. You just have
to pick VDPAU from two dropdown lists. Also one of the main selling
points for VDPAU isn't just the hardware decoder, but also the
de-interlacers. Not all cards can do all of the de-interlacers. So it
would probably be necessary to make VDPAU High and VDPAU Low profiles.
Either way people will likely need to go in and adjust the
de-interlacers for their particular system. But I suppose it would be
nice to have a couple of predefined profiles in there to start with.
