I have a remote control question I have not been able to find the answer to. I have a 522 in Dual Mode. I have TV1 outputting S-video to one TV. I have TV2 outputting on RG6 and split to 2 TVs mirroring each other. I just added RG6 to the TV1 output to mirror TV1 on another screen. So my IR remote works TV1, but I cannot get my extra UHF remote to operate TV1. TV1 frequency is 5, TV2 frequency is 7. Is there a way to only change the frequency the remote is outputting, when I try to change it it changes TV2 frequency to 5. I then tried flipping the chip over and it will then operate TV1, but when I go to the other room to the mirrored TV the remote loses funcionality, almost like it is acting like an IR remote. I hope this is clear enough. Any help or advice would be greatly appreciated.
