When we lived in Oregon and now in Boulder, we got the Pac12 National feed in HD and then the P12 regional channel as well (only in SD).
I've heard a lot of complaining about folks not being able to watch the games on their regional P12 network, but why not watch the national feed?
When I had Comcast in Denver I only got Pac12 Mountain. To get the national feed you had to have the sports pack.
