Adobe Flash player screwy?

since yesterday the videos on south park studios have been really slow, about the last half of the videos are slow in Frame rate, not in connection, it looks more like a slideshow even the browser itself is slow all 3 of them (IE, FireFox, and Google Chrome) but the sounds are 100% in quality (no skipping). I've done a registry scan/repair/defrag, I've cleaned out all my junk files, uninstalled and reinstalled Flash Player, and I've even increased the "Local Storage" to "Unlimited" and no difference that I can see, anything to help?
