I am having a video problem with Youtube. I figured this would be a good place to ask about it.

I get these odd artifacts that are hard to describe, but I've tried to capture them in the attached screen capture. Any ideas?

*edit*
Damn! It doesn't convey! That's really odd. They were there when I pasted it into PSP, but now when I look at the image after attaching it to the post, it looks correct! This is odd...
