Hello, I have had 2 Series 3 Tivos working great (minus a few hard drive replacements) for as long as they have been released. My service is Charter in St. Louis, MO. Even have worked great with the tuning adapter since they went to the switched service. About a month ago, channel 891 (PBTV) stopped working. When I change to the channel, I would see about .5 seconds of video followed by the grey bordered screen with a black inside. At the top it says "This screen is displayed on behalf of your cable provider. CableCARD 2). Inside it says "In order to start cable service for this device, please contact your cable provider 1-888-438-2427. Then is shows CableCARD(tm), Host, Data, UnitAddress, etc. The Service rep came out (of course never even heard of a Tivo or cableCARD), checked my signal and after 2 hours I just said don't worry, cancel the channel. Then the same thing started happening recently with HBO, Cinemax, and Starz. Service Rep out today replaced cableCARDS, tuning adapters, checked/verified signals, can't figure it out. They were going to try to elevate it, but I don't have high hopes (feel like I might end up with U-Verse or DirecTV). Anybody have anything like this happen and if so, any suggestions on what to tell Charter to get it fixed?
