Double Video playback problem

Hi,

I searched the forums but could not find a solution. Since I have installed the latest Flash player with firefox, the videos I watch with it are "double", there is one video on top and one on the bottom with a green line in the center. I can play games with no problem, but any video I watch with flash has this "double" issue.

THe issue occus with firefox and opera. IE works FINE (but I hate IE). I uninstalled the flash player, firefox (deleteing the folder that was left behind as well), and opera, turned off my antivirus (AVG) and then proceeded to re-install with no luck, same issue.

I'm using an up to date XP professiosnal.

Please help!
