I was VERY, VERY, VERY excited when I found out, that the latest Intel Graphics driver supported DXVA (DirectX Video Acceleration) on Windows XP, which I have on my subnotebook.
The version is 188.8.131.5203 (184.108.40.20603), and the release notes are to be read here: http://downloadmirror.intel.com/19412/eng/relnotes_xp_gfx.htm
It says there as a new feature:
"Hardware Accelerated VC-1 (VLD) & H.264 (VLD) Video Decode in Windows XP"
Now, I tried with Mediaplayer Classic Homecinema, both with Haali Media Splitter + FFDshow and internal splitters/decoders, no luck. Then I tried KMPlayer, no luck. VLC no luck. Windows Media Player with FFDshow+DXVA enabled for H.264+VC-1.. no luck. It just doesn't seem to work at all. DXVA Checker says it's there, if I understand its output correctly, but still..
I guess I'm just doing something wrong here or the driver doesn't deliver any DXVA capabilities? I would like to ask, what software configuration I should use exactly, to get DXVA to work.
My aim is to play Blu-Rays on the subnotebook, since a BD burner is built-in, but my CPU alone is simply too weak to handle the load of a 1080p BD. At the moment I am testing with MKV container files with H.264/AVC video streams inside.
