YouTube is blocked live for me, since the first race day. It says it's blocked in the US, but it may be regional. I haven't been able to see the races on youTube until 6 hrs later. If I go straight there over coffee in the morning, I have often seen the race before I hear the result.
If I happen to be able to catch them live, the NBC Sports iPad/iPhone app has worked well. It's free, but you must sigh up via your cable TV account. You don't pay your cable carrier, you just need to have already paid for the service indirectly.
While not live, it's nice to catch them on Youtube without commercials.
