Just announced - the channel for the Big Ten Network will be channel 333 on Time Warner Cable. The alternate feed will be on channel 334.
If you do not have a cable box, you still can see the game! It's on channel 77.
The above information, courtesy Time Warner Cable pre-recorded message.
UPDATE - High-def feeds supposedly will be on Channel 757, but they "might" not have the HD set up until Monday, too late for Game 1, but cool for the following games.
