Have cancelled my Setanta Freeview. But after testing their Setanta Broadband I have subscribed to that. It's £7.99 and the stream is great (I have a 2mb connection). All Setanta channels are available through it and they have all their previous fights to watch instantly.
It streams Great.

I had to get it as I want to watch the Pavlik vs Taylor fight Live without using the unreliable sopcast.
