After probably 10 years or so, I'm cancelling Spectrum TV and my Tivo account to go to streaming. I may be back...but probably not. My question is, once I cancel my Tivo and cable account, what can I expect to do with this Tivo Premier? Right now I have my outdoor antenna running through it for additional locals. I'm pretty sure I will lose the guide info, but is there a way to use it solely for this OTA viewing? On the other hand without a cable card it may be totally useless anyway. Any thoughts?
