I've just pushed dxva2 support into xbmc svn using these changes. It seems
to be working for anything encoded by x264 asfar as I can tell. 

Pure bluerays seems to have troubles (the one i have anyway), get weird
corruptions at lower half of video.

Also anything encoded by quicktime is also not playing nice. Normally just
green screen, and errors about failing to execute buffer.

VC1 seems to work for the few samples I've tried it on.
