Hello, I have had my tivo series 3 for about 2 years and until recently i have never had cable cards in my tivo. Before I put the cable cards in everything worked fine but I wouldn't receive HD channels. I decided to finally put the the cable cards in and I thought everything was working fine until I realized that certain channels didn't have any guide information. I receive all of my channels but channels 30-77 don't have any guide information and just display "to be announced". THis is a problem because those channels have certain shows that needed to be recorded. I called Time warner cable and the tech came over and said he fixed it and that it would take a couple hours for the guide information to updated. Still no update and I rebooted the Tivo twice already. Does anyone have any suggestions?
