I have the setanta sports pack rather than Sky sports for NASN (North American Sports network) and the coverage is really good.
To go through the channels
NASN - If you love american sports this is a fantastic channel. they have exclusive rights to the ice hockey and show loads of live games. When the baseball season starts, also loads of games. In addition ESPN have a huge interest in NASN now and are pumping a lot of their programmes through as well. If you hadn't guessed i love this channel.
Setanta Golf - Started in Feb as they nicked the US PGA off sky. Excellent coverage and lots of live tournaments.
Setanta sports 1 & 2 - Quite a variety of different sports including gaelic sports, 6 nations highlights and the Ozzy RL (which you were asking about). The feed and the commentary is from down under so pretty life like if you can get passed the accents.
Celtic & rangers TV - Only of any use if you are a fan of either.
Racing UK & Racing World - If you like your horses these are good, if you don't not much to see here.
Setanta ireland - usually blocked out as seems to be for the irish subscribers.
Not forgetting of course that from August they also have the premiership, not as much as sky but footie non the less.
These are all my opinions but i hope it helps.
