Hi Guys, I hope this is an easy question for you all

What exactly is the difference between the 2210 and 2200 cards?
I'm looking at adding a dual tuner to my HTPC and have heard good things about the 2200. However I've seen the 2210 floating around too

Any idea what is different about these two cards? I'm a little stumped as to which one I should buy

Thanks!
