picture quality is dependent on connection speed. if you get a nice cable connection, it is good enough to watch full screen without distortion. i would say about the quality of a vhs tape. but if oy ushrink it down more, the better it gets. i have actually watched this on my GSM cingular air card when i didnt have the 3G signal. so, as long as you have a quick connection, you should be ok.
also…if you have a broadband phone/pda like a treo, you can get it on that too. so you can watch the game while youre at it. i havent tried this though. i dont have anything that fancy.
