I want to use both and I thought the "x" remotes could do both? I had 3 remotes on the HR-500 all woking with my Sammy but I can't get the 3 new "x" remotes to do RF at all. I they all do IR but if I change one and it doesn't work I can't just copy the setting back because....well they'll be gone!!! No biggy starting over but I'm trying to avoid do that for all 3. Is there an easy way to enable RF to test and then go back if I can't get it to work?
