I have a similar problem. I have 'basic' cable up through channel 99, then an expanded digital for 30 or so more channels with on demand service available. i tried all 3 of the different choices available for me; the basic channels are fine, most of the digital are ok, but at least 2 digital channels are missing (both for kids shows, Noggin and Nick Kids). Tivo says I get the channel, but i get nothing but a black screen on those channels now.
