I have the above hardware and when running through the Guided Setup, I get to a point where it asks about controlling the directv receiver. It says it needs a cable plugged into the tivo and receiver. The receiver does not have these ports. Do I need a different receiver?

#UPDATE#

I've got the tivo working now. I just have to change the channel on both devices manually. I've noticed that the enter button on the tivo remote sends a signal to the receiver, but numbers don't work. Is there a way I can input an IR code? I've looked at the compatibility thread and the tivo support link on changing the IR code does not work.
