Could this method of GPU video acceleration be something for the Windows port of XBMC?:

subject [FFmpeg-devel] New project using Ffmpeg with DXVA
I'm one of the project administrator of Media Player Classic - Homecinema, a fork from original Guliverkli project. We have used ffmpeg to add a new internal video decoder inside mpc for software decoding, but we have also the possibility to accelerate H264 and VC1 decoding using DXVA hardware acceleration (only video card with bitstream acceleration are supported for the moment).
This project is present on SourceForge at this address http://sourceforge.net/projects/mpc-hc/ and the first release using ffmpeg decoder will be available soon (final testing stage).
Could you please add mpc-hc on the list of ffmpeg powered project.
Thank you very much for you great works
