I've got a Toshiba branded TIVO with a DVD player and DVD burner in it, and I'm considering adding a HDTivo to the setup. The only DVD player in the room is in the current TIVO, and there aren't DVD HD Tivos that I can find, so I was wondering if you can set up both an older Series-2 type tivo with a HD Tivo and be able to use both at the same time without running into remote-control compatibility issues.
