Video no longer working for AVI, MPG.. only audio..

I upgraded my video card drivers recently (ATI Radeon 9600) after uninstalling my old video card drivers, and now when I play AVI or MPG or VOB files in VLC or WinAmp or Windows Media Player, there is no video, only audio. I can still play MOV files in Quicktime just fine. I tried uninstalling all my codecs and reinstalling the newest version of K-Lite codecs but that didn't help. Any ideas on how I can fix this? I know my video card is old so maybe this is a sign that I need to just buy a new video card.. in the meantime is there some way I can access an older version of ATI Radeon 9600 drivers, if there is no other fix? Thank you.

(since I'm not sure if it is a straight driver problem, I stuck this in the software forum... sorry if that was a mistake)

 

i figured it out.. i used the catalyst control center. i can't figure out how to delete this thread.. any mods feel free to delete this whole thread, thank you.
