Trying to record show to remote Premiere using guide, how?

I have 2 Tivo Premieres' connected to my home network in family room and bedroom.

I am tying to record a show from my family room Premiere to my bedroom premiere using the guide.

However, I can't get it work. I goto the other Tivo on the screen but when I press the guide it only records to the local Tivo.

What I am missing here? Please help. Thanks.
