I have several TVs and viewing areas. In one of those I'm already employing an RF system. It's the URC200 Universal Remote with the MRF-100 RF module. I would like to put a second RF remote in the house and was wondering if anyone knew if you could have the remote RF module that comes with the URC-9910 in the same house with the MRF-100 without them interfering with each other? I can't find the frequency info for the 9910 anywhere.
