Advertisements At the end of January I got a "Tivo Service Notice" emailed to me explaining that my local cable company Comcast was in the process of converting to an all digital format and that I would need a cable box to view channels, although basic channels would continue to be broadcast in analog format. Today my Tivo notified me that it could not find my cable lineup and prompted me to go through the process of identifying a new cable lineup. This is the process where it shows you a channel and asks you to confirm if that channel is what it suggests. Based on my answers it switched me to a lineup that is wrong. I called Comcast and was told that since I have Basic Cable the choice of whether I use a digital box is up to me, that the channels I receive aren't being converted to digital with the exception of 1 channel. What is the process to get Tivo to recognize that the lineup I had previously is still correct?
