Here's my situation. I have an old tivo with MSD grandfathered at $6.95/mo no commit. I have a newer DT tivo that had a one-year prepay and now is at $16.95. Here's what I'd like to do: Buy a new DT tivo to replace the old one. Transfer the newer DT tivo to the MSD account, and get a prepay package with hte newest Tivo. Can I do this? What are the steps so this doesn't backfire on me?
