Starting in June I tried to add a Tivo Premiere in addition to my 8 year old Series 2. After 5 tech visits, 8 cable cards, and 2 Tivo Premiers the Premiere got sent back to Tivo. The techs were also telling me about other people on their system that had more that 20 cable cards tried with no success. They say that no Series 4 Tivos have ever worked on Optimum West (Formerly Bresnan). I purchased a Tivo HD (series 3) off Ebay, and the first cable card tried worked perfectly the first time. Anyone else had similar problems with a Tivo Premier on their network?
