The geforce 9400/9300 is great for laptops. It offers full acceleration, and is capable of 1080 bluray playback.
You could also try updating directx as well. I know DivX has beta codecs out that can pass the video through directx, making acceleration possible with any video card. link http://labs.divx.com/mkvwin7preview
