Advertisements Is it possible to connect an older single tuner Series 2 to a General Instrument StarFone SFT-2 cable box without an IR cable or serial cable and get it to work? A relative has this setup and insists it used to work and doesn't remember using an IR cable. The Tivo had to be repaired and since its return they can't get past the IR cable question in the setup process. I keep insisting they must of had an IR cable before, but they keep saying there wasn't one connected, not even a serial cable. I'm stumped because as far as I know the StarFone would need an IR cable for the Tivo remote to change the channels. I just don't get how it worked before without one. My relative said their previous cable box didn't need an IR cable and they don't remember the current cable box using an IR cable. Maybe there was a cable that plugged into both the StarFone cable box and Tivo, then at some point their cable company did service and mistakenly took the cable.
