clonning picture problem (on secondary device)

I have GF 2MX 400, newest drivers and problem ... when I am clonning picture (TV - secondary device) everything seems to be ok, but
when I am watching movie I can see only the window without movie inside. After setting TV as a master device and monitor as a
secondary I can see on TV everything with movie inside window (Windows media player and other players ) but then on my monitor I can
see every window but no movie inside . I can see movie only on my master device ! . How to set and what to get move on collning
picture, on a master and on a secondary picture. I want to say that it was everything ok when I had old drivers, when drivets wasn't
looking like windows from win. XP, it was 2 years ago probably. With this "newest" drivers (or mayby it is windows XP error) it is
not going like it should.. Please help me.
