i don't understand... you have some driver that they don't work????........

did you try any driver from this site....... did you replace modified INF with original one?

can you tell more about your problem......... what error comes when you try to install them?

Yes... i tried both...(VMR on and off)..

with VMR on , the colors is washed out, black is gray in video.....and video looks like i'm playing it in 16bit color quality (instead of 32bit).......

with VMR off, black is black(not gary) , but still looks like it's in 16bit color quality..........

thanks for your replay.....
