Converter Box with 810H

I've got a Panasonic 810H Series 2, and have upgraded the Operating 
system to 9.3.1.  When I reset the system (erasing everything) and 
selected Antenna, setup asked if I had a converter box, but didn't ask 
which one.

Is there a place in the setup menus I can select/change the  
brand/model of the converter box?

Also, does anyone have a list of converter boxes compatible (that is, 
that can be controlled by TiVo) with the 810H?
