Good day, i have recently purchased a MX-600 remote withe the MRF-100 base station. I have a flat screen on the main floor and all of the components in the basement. the remote works fine, but i also have a TV and sat receivers in the basement, when i control the main floor tv it also changes channels etc. on the basement tv(sat receivers are same as main floor). Is there anything i can do about this as of course the kids are going crazy in the basement as i change channels upstairs i also change their tv channels.
