You're lucky, our Time Warner doesn't have any of those channels in HD.
I'm at the tipping point to go dish myself. Shit, we don't even get the NFL Network. 
Yep, no NFL Network, no NFL Sunday Ticket, once I move into my gf's house I'm switching to DTV. I'm tired of waiting for cable to 'catch up' when now the Dish companies are offering 2-3x the amount of channels in HD AND are offering them in full resolution now.
Cable is too far behind to catch up at this point, they will just be my internet provider in the future.
