INT-422-3 Device A: Flirc on 1st Gen Fire TV, Device B: Xbox One, Device C: WMC, Device D, Audio Reciever. I've tried a lot of different codes (Blu-ray players, Satellite boxes, Roku) and successfully programmed them to the Flirc and I'm able to control the Fire TV just fine with those codes. But when I switch over to Device C or use my original WMC remote, The Flirc dongle is still sending those commands to the Fire TV.
