www.channelsurfing.net. Several links will only work on Internet Explorer. Great option for out of market NFL games as well.
Other options include TVU player, SopCast, or Ziggy TV.... try a google search for these three options.
I use all of these options on a regular basis for sporting events around the world. Even hooked up a company laptop to allow our hotel guest in Costa Rica to watch the Super Bowl this year. Our cable company here pirates ABC, NBC, CBS, and FOX networks from Denver but make events such as the Olympics, NBA Finals, and Super Bowl "pay per view" events at their own discression. We F'ed the man this year by using my computer for the Super Bowl.
A little practice and experimenting and you should be able to view the game with great picture and sound and in real time. Edit: just remembered another option.... www.justin.tv
