Advertisements If I just plug in my new Tivo HD and put on the Tivo adapter, plug it into a TV, will the Tivo update the software over the net if I do not have a subscription set up yet? I am not sure when I will get the FiosTV. I am trying to get in as an employee hookup while they are still launching it here in Pittsburgh. If I cannot get onboard that way, it will probably be launched around late October or early November. I just wondered if I should get it set up beforehand, and if you can do that.
