I can't watch videos on Youtube anymore.

So a few months back, I lost the ability to watch any videos in Full screen mode from a webpage, and now I can't even watch the videos anymore starting last night. I get either a blackscreen with a few colored lines scrambled about or nothing at all, even the play/stop icons have disappeared though I can still interact with them. I still get audio with no problems I just seem to have lost all picture. Any suggestions?

I already updated Flash Player and Divx. I'm also working on Windows XP if that might have something to do with it.

It might be a problem with your graphics card's driver. I would try updating it.

Is this just Youtube or all streaming video sites? What about other Flash applications, such as games?

I don't play too many flash games, but it does look like Unicorn Attack is far more sluggish than usual and its frame rate dropped.

What browser are you using? You may want to try updating to the latest version. That and updating display drivers would be my suggestion.

I updated my driver to a new one and I was able to see video again but the quality was rather poor and it had a hard time making out lettering. The Interface section of videos looked really bad. Then I checked to see if there were and Windows update for the driver and installed it and now I'm back to the issue of being unable to see video. :(
