Having the same kind of problem as Burninator. However, my connection shouldn't be the problem.
I am trying to watch on a wireless connection on my Xbox. It probably loads higher than the lowest quality (which is unwatchable, IMO) 1 in 6 times, and hardly maintains it.
I'll try a wired connection. If it HAS to be wired, then I am going to be pretty PO'd.
EDIT: Same BS on the wired connection. Lame.
