I have the occasional problem as well (I'm also on a Mac.) The video from PNG's Freaky Friday was an example. I am not sure what causes this. It does not happen very often, so I simply shrug my shoulders. I do find, however, that sometimes FireFox handles streaming video better than Safari. What browser are you using, B-line?
