Here's a handy link to help you keep track of what channels the games are on :

I use this site during the Premier League season, and the guy who maintains it keeps it very up to date.
There is also radio information, which may come in handy if you're in the car (or at a workplace where audio is OK but video is taboo) and want to catch some of the action. My survival strategy for the tournament will consist of my Slingbox so I can stream the games from home to my desktop at work, and the TuneIn Radio app for the iPhone, which can pick up the streams from the TSN/Team radio stations while I'm in the car.
