hah, yes? yes what?
Well, I seem to have the same issue. I get a black screen where a video should be playing. However, I don't have to kill the process; I can still access the menu and try to select another video, but have the same results. Sometimes a comercial will play (specifically with the movie trailers section) but after the comercial I get black screen; and its blank where the movie title should be.
I haven't actually tried firefox; but I know with a win32 box it works fine in IE. (hulu desktop doesnt work on the win32 box either)
