Dualview - how to play a game + watch a video

Dear forumers!

A usual setup for me is that I play some PC Game and my girlfriend watches some movie.
I have a 8800 GT a Samsung Syncmaster 2232BW, and a Samsung LCD TV with analog connection available.

So what i would like to achieve now, I had been doing for the past year no problem before i reinstalled windows!
I was able to play WoW or CIV IV or whatever PC game full screen on my monitor, while I was able to watch a .avi or whatever video file on the TV simultaneously.

Since I had reinstalled win, I can't do the same!

after I start the movie and then i start the PC game, the movie either freezes or the tv screen goes blank
then if I shut down the pc game the movie continues.

I have the exact same hardver setup now as before, same videocard + monitor + LCD TV.

I suspect the problem comes from either the driver or some wrong setup issue because these are the only things that changed after the winreinstall.


Any ideas guys?

Do I need some specific driver?
Should I retry some 1 year old ones?
Should I get some appllication to help me?
btw what I want, the simultanous pc game + video is it even officially possible?


pls help me, ms GF is killing me!)
