Advertisements Tomorrow I am getting a new Edge for Antenna with Lifetime from Channel Master. I see on the Tivo website that two old lifetime units are still on my account. One went to the dumpster years ago and I gave the other to a relative who never used it. Is there any reason to register my new device with Tivo? If I should have guide problems, I could always just submit a ticket with one of the old Lifetime's receiver number.
