I have had non-stop problems since I purchased my TiVo Premiere in April. I have Charter cable service and they have made about 10 visits and swapped out my tuning adapter 3 times, most recently yesterday. It is a Motorola tuning adapter. When I turn on my TV and AV receiver I get a TiVo message on the screen reading "A tuning adapter is attached to the DVR - to verify that your DVR is receiving all the channels in your subscriber package, test your tuning adapter" I skip this step and select "Continue" to test later. (When I do test, all the channels are received.) Then, while watching TV - no matter what channel - the above message pops up again and the TV signal is dropped. If I am recording 1 program or 2 programs the recording is stopped. This happens whether I am watching TV or when TiVo is recording programs I have selected and I am not watching. I love the TiVo Premiere, but this has gone on for 6 months! Charter is clueless - the first techs who installed in April told me they had never installed a cable card in a TiVo - I gave them the instructions from the TiVo box! Then I discovered I wasn't receiving all of the channels I subscribed to and they came back out and told me I needed a tuning adapter, again telling me they had never installed a TA with a TiVo but they installed it, and all the channels were being received. But the above problems began happening right away-dropping the signal. They came out again and the tech told me that the previous tech had installed the TA incorrectly, so he supposedly corrected that. Then the same problems again. Several subsequent visits by Charter techs have given me a variety of reasons for this problem. They have checked and verified all the lines in the house and are certain there is not a problem with the signal strength. They have told me that they have monitored the transmission and have seen fluctuations in signal strength but that the problem was not in the house, it was on the line coming to the house. None of the other TVs in the house drop the signal ever, but they are are not HD TVs, they are analog. I was told that the HD digital signal is very sensitive to fluctuations and that this is what is causing the signal to drop. HELP!
