Viewing videos on the pc problem

Hello all. I have an issue that just started happening when I upgraded my video drivers. I have a dual monitor setup, and when I watch a video with media player, its a blank picture on my main monitor, but if I drag the media player over to the other monitor, I have video. I am kinda lost as to what I changed to cause this. I need the movies to play on my main monitor cuz its a 22 inch flat panel, and the other is a 16 inch crt. It was working yesterday before I upgraded my ati vid drivers.

**edit** NM, it was stupid setting in the catalyst control center....what a POS
