Advertisements am a consumer who is having tremendous difficulty with my hi-def tivo unit. The unit cannot detect a dial tone in order to update program information. At first they determined that the problem was the tivo unit - that it was occupying the phone line and so could not connect, and so I paid $75.00 for a new unit which connected once when we switched the 2 cable cards to it and now will not connect again. Tivo says that it must be the phone line or the specific phone jack. I have tried another jack which also did not work, and called my phone line supporter who said if I was calling them on the line than there obviously was no problem with the line. And, no, I do not have DSL on that same line. So... I am at a loss and do not know what to try next! Has anyone experienced this?
