How does it work with the Insignia Roku TV
I am confused. Is the TIVO a recording device or an antenna? I am in need of a device to record local programs received through an OTA antenna. I have the Insignia Smart Tv that has a Roku box built in. I watch both streaming via wifi and OTA via antenna and watch mainly the PBS channel which I access both through the streaming ROKU PBS station as well as OTA on my local PBS channel with an enhanced antenna. Problem is that I still cannot watch my favorite shows because (a ) the streaming on the ROKU PBS channel is too delayed (ie. I don't want to watch the PBS NEWS HOUR a day late) and (b) I am not home when the shows are broadcast over the air. Can I use a TIVO to record my show off of the over the air broadcast ? If so, does the TIVO obviate the need for the good antenna that I am using for OTA channels so that I can use that antenna on another tv?
