The Charter guys showed up this AM. They had never done a Tivo before, but I had it all set up for them. Put the first card in, and after a few minutes (and a 161-4 error) it came up. Dito for card 2. So, I'm golden. Best of all, they took that piece of (@&#% Moxi with them. Master - hook up the box and go through a guided setup as if it had no HD channels, once this is done you a finished until the Cable Cards show up.
