Atlanta - I've had my series3 since January. I've just been using it with analog cable until I purchase a HDTV. Over the last few weeks comcast has been trying to get everyone to move to digital. So I agreed. They required I have a tech install the cable cards. He has no clue. He is an independent contractor for Comcast . We follow the TiVo directions. He calls Comcast and they say they have activated the cards but they still don't work. His management says the TiVo is not his problem and Comcast says the cards are active and that I need to program the channels on my TV! Comcast does not have a clue!!! So he leaves me with the Cablecards that don't work... Here is what happens. TiVo sees the cards, no problem. I keep getting an error acquiring channels. The message says "The DVR is unable to acquire channel information from the CableCard.....' The first time it looked like it was acquiring the channels. it counted up to 385 channels loaded and then stopped. Since then, nothing. I have reset the box, done the guided setup, but it will not acquire the channels Any suggestions?
