This all explains how desperately Tivo clung onto my subscription. I wanted to sell my SA Tivo to my old roommate who has been hurting since I took it with me. According to their website, the only way I could do that was to cancel my subscription, then he'll sign up with the box himself as a new subscriber.
So I called up Tivo and told them what I wanted to do. After a couple minutes of talking to the rep, he put me on hold for what seemed like around 10 minutes. When he came back, he said "So how's this, we'll lower your monthly fee to $6.99."

Well, I knew my old roommate wasn't sure if he would want to pay the $13, so I said OK

All I had to do was go into my online account, and change my details with him one by one (first contact info, then credit card, etc), ending with having him change his password. It's like I no longer owned the Tivo!
