Helyreállt az eredeti állapot, tehát működik, x264-et gyorsít (kb 10x), viszont az mpeg4 nagyon nagy CPU-t zabál.
Kínlódik az mplayer tehát:

Egyébként te a 64 bites változatot próbálod, ez különbség. Megnéznéd hogy a sima mpeg4-es videók neked mit csinálnak?
Mellesleg az XvBA leírásában az van hogy h264 és WMV9-et támogat csak... Ha így van, akkor jó lenne beállítani valahogy, hogy a GPU-t csak az x264 használja. De hogyan
