Does anyone know which network will broadcast these events or where I can find these online? the 1500m FreeStyle qualifying heats start tomorrow morning and the final is on Saturday...

nbcolympics.com in the U.S., but I haven't had much luck with the site. The videos are slow to start and very jerky with many pauses.
