I just pm'd kaiser to give you more specifics but in the meantime if you have TW you simply call them and ask to be upgraded to get Big10 Network. Then you cancel it on Sunday. It'll cost you .25 cents
BTN has a useful Gamefinder device where you enter your zip code and cable or Satellite provider, and it will show you what Channel the game's on. As mentioned above, it'll be on Channel 610 on Directv.
