Probably not. You are doing IPTV, so the TV boxes in your home are assigned an IP addr, just like the computers.
They either connect over the WiFi, or over traditional coax cable.
I have the Residential Gateway, but I think I have mine set so that it knows there is another router in the home.
I use the Residential Gateway as internet access for my wife and I. The router I've attached to it is for the kids and guests and turns it's WiFi radio on and off on a schedule.
So you can use a second router with the RG, you just get another router hop for any traffic.
The way I have things set up is as follows:
Internet
|
|
RG ==== 192.168.1.0/24 (Parents/uVerse Network)
|
|
|
Kids Router ==== 192.168.2.0/24
I'd have to check my settings at home to see what I changed on the router to do this if you are interested in this solution.

Reason being is that I'd like my own router to do things like NAT and DHCP.
