Multi-GPU Mode problems (Answer please before wednesday)

Hello I've bought an EVGA 9800 GX2 but when on Multi-Displaymode (as apposed to Multi-GPU Mode) movies will run at say 15fps, its ok on multi-gpu mode.

It does it on all movies, even in the windows environment

Is this just the EVGA series that do this?
I have the latest drivers from the nvidia website.



Thanks

I BEG YOU
