Programming suppliers like Turner/Time-Warner are demanding ever higher “carriage fees” forcing satellite/cabe providers to raise rates. These programming fee contract fights are becoming common...the channels you mention will probably return within a month, take a break from the Clintoon News Network! ;-) You would probably pay more for DirecTV (after the 24 mo. “promo” period..my nothing special, no HBO, etc, DirecTV package is $119.00/mo.

My directv everything package only costs me $140. That’s only because I was going to cancel all the premium channels so they reduced them. I finally dropped dish when they cut off FX in the middle of Sons of Anarchy season. It took some getting used to because of the different equipment but I’m satisfied.
