The ITV feed for TSN usually starts during the formation lap and ends pretty much 20s after the race is over. I don't know if TSN reachs down to the US though. I know for a fact that I would not watch the races with those bozos on SpeedVision announcing it. There is a really good site that does reall time updates to F1 races that has a diagram of the track and points out where events happen! It is pretty cool and I usually have it going while I watch the race.
