CBS Sportsline/CSTV.com are once more offering the 1st and 2nd round games (not being shown in your area) of the NCAA Tournament on streaming video. This year it is free.
I mentioned it a while back, but it is getting closer and they are making claims that they only have limited capacity. You have to sign-up for it, but if you did it last year or have a CBS Sportsline sign-in, you can use that to sign-up for it.
The streaming quality is about the same as ESPN’s computer feed, but hey it’s free.
