Two weeks ago Time Warner finally added the NFL Network. I cannot make it work on either TV through Tivo. Both boxes have cable cards and they tell me it's not their problem. Anyone had issues with this? I've restarted both boxes; done the programming from ground zero and still nothing. I'm hesitant to pull out the cable cards - they were installed by TW. I've been waiting years for this channel and nothing. I'm also sick of the cable card losing sound frequently. Seems we need a better alternative.
