I just tried upgrading to the new HD Tivo from DirecTV. They told me I had to have a phone line. I questioned if I could take it to a phone line for the initial setup. Again multiple people said it had to have one to continue to get local channels. They said it did not until a couple weeks ago when an upgrade came down and now every couple weeks it needs to make a call or else it shuts down your local channels. Anyone know if this is definitely true or could I take to parents do the call thru the phone line and bring back and just have the nagging message, but it would work fine????
