Safari Choppiness

[evan0g]

Hello again, I'm having issues with flash videos in Safari so I hope someone can help me out. I have a Mid-2009 Macbook Pro with 8gb RAM, running Lion, Safari 5.1, and my ISP speed is 50mbps. Basically, when I first start watching a movie, say on Novamov or other flash playback websites, after half an hour or so, the video gets progressively choppy. I thought it might be that my lappy was overheating since I usually have it on my bed when I watch a movie so I bought a coolpad, but that has not helped. The movie is usually full-screened and is on the active window/tab if that helps. Any ideas how to fix the choppiness? Thanks

I have the exact same problem. Never used to happen pre-lion. Anyone else having this?
