Out in Sheepland we're deprived (not depraved) and don't yet have fibre.
Using bog standard BB, I found Sopcast by far the best, most reliable application, but as Greez points out, there aren't as many streams these days. Sometimes it will just go off part way through a game as well.

I find Acestream a bit iffy, I have a lot of buffering problems with it, even though I've tweaked it a bit. It does depend on the stream, some are much better than others.
So I usually go to a pub with it on. That's the only reason-honest.
