PPV events and livestreaming - what's working best for you?

I assume I'm like most people who try to watch a PPV event such as a UFC or boxing card via a livestream, you start at www.justin.tv and bounce around until you find a channel that's relatively stable and hope that it lasts the entire event.

Does anybody here have any connections to better sites for viewing streams? Possibly ones that require an invite/password? If you do please help a brutha out. ;)

Thanks.
