I'm in the SoCal area; use Time Warner Cable. Just plunked down 300 for a TIVO HD. Time Warner cannot seem to figure out how to get the cable cards to work. I only get half the channels. I've done my research and KNOW that the card is not "paired" to my TIVO set but TWC keeps saying it is and they keep sending out techs to my house. Be careful - the folks at the cable company are not trained in these complicated cable card issues.
