Windows 7 - 7600GT aero problem

Aero is wonderful, wonderful... except when i open an avi file, a film. I get the film fine but with green static lines throughout if i make the window too large. if i go to 16 bit high colour, then all is well, but at 32 bit true color this happens. otherwise, this is fine. can anyone tell me anything about this problem/

thanks.

edit: been checking on google, one user reported similar problem with VLC and changed a config in the program by setting video output to DirectX. this in some way kills aero. tried it in VLC and it works. however i use BS player normally and have this problem in any player.

thinking my video card is not up to the task.

Your 7600gt should be nire than capible of running Areo. Which driver are you currently using?

i updated to the latest 8.16.11.9107 after experiencing this. I am beginning to think it is the card itself as it occasionally for no reason displayed this same behaviour in win XP.
