codec is easy, install mediainfo

vdpau has limitatations on codec, and in some cases depends on card
(there are three "featuresets")

Even then with some featuresets with some codecs which otherwise work,
but don't support particular video sizes.

the nvidia readme has more info, in particular
http://us.download.nvidia.com/XFree86/Linux-x86/280.13/README/supportedchips.html
and http://us.download.nvidia.com/XFree86/Linux-x86/280.13/README/vdpausupport.html
