Sorry, I can't help on the original request, but thought that I'd pass along some info for other interested people that they can watch March Madness over the internet at the
NCAA website. If you wanna use that method to watch games then try to connect to it as early as possible because otherwise you may have to wait in a queuing system (unless you signed up a few weeks ago, in which case you get VIP access). You can then choose which game to watch, and flip around whenever you want.
I used it a lot last year, it's pretty good, and apparently they've improved the video quality this year, but we'll find out this evening. Unfortunately, you can't watch any of the Final Four weekend on that, though.
