BitTorrent tracker aggregator, dedicated to TV shows, if it airs it's in here (and fast), if you miss an episode you will find it here (they even post webisodes for series that got canceled)
Zattoo is live TV on your PC - it's the football game as you chat, the news as you email, and your favorite soap as you pay your bills. Zattoo is also TV when you don't have a TV - it's the channels you want, when you want, where you want.
