Advertisements I have a tivo series 3 and is about to "lose all HD channels" because comcast is switching to mpeg4. Tivo web site says they have a special deal for tivo owners who are forced to upgrade because of this. Does anyone know how special this special deal is? I also have life time service on my series 3 and need to transfer it to the new tivo. Alternately, if I switch ISP and cable to frontier, would I be able to continue using my series 3?
