ATI Input Connectors and Video Flickering/Skipping

I have a dell dimension 8200 with an ATI 9600 All in Wonder Card. It used to ran perfectly well until I have driver issues. Since I fixed the driver issues the TV mode works perfectly fine but whenever I switch to an input connector be it composite cables, video cables or svideo the movie I am playing will only display the first frame begin to flick and get stuck on and stay flickering for ever. I can hear the sound in the background and its smoth like the dvd is still playing however the screen still shows the first frame flickering rapidly like its stuck or like a cd skipping. Any help on what might be causing this will be appreciated. It only does does when i switch the input to the connectors. It works fine in TV mode.
