I have a friend that has the 4 tuner Roamio that can either do cable or OTA. She's looking to lower her Spectrum bill and has found out that if she drops TV for a month, she can come back as a new subscriber even though she is keeping her internet. What I'm looking to find out is can we switch the TiVo to OTA and still leave the cablecard in the TiVo. I do realize that we won't pull any cable channels and have to hook up an antenna. I don't want to chance turning the card in and then Spectrum being "unable" to find a new one. Before we cancel TV, we're going to try and see if Spectrum Choice will work with a cablecard. I've seen mixed reports on that. Finally she has absolutely no interest in switching to any streaming service for live TV. I have been suggesting that for over a year with no success. If she can't watch something through her TiVo, she won't watch it. And based on forum reports, she may be the only person in the world that has no problems streaming Netflix and Hulu on her TiVo.
