Several questions: 1. Are the accessory codes the same for RC6x and RC7x remotes? 2. *Are there specific printed step-by-step programming instructions anywhere for these remotes anymore (not requiring an operating DVR) to help set up the remotes? 3. *If the codes are the same, can anyone remember the command sequence to get the RC6x remote to "play back" the programmed code for the device being controlled, so as not to have to try looking it up again? * I just found the link that Rat Patrol had sent for the RC6x 48-page PDF manual. Thank goodness that link still worked, as I'm having absolutely no luck searching online for this info!! (I'll be sifting through for the answer to 3.) Maybe there's one of these PDFs for the RC7x? Specifically, I'm trying to get my AVR mute/vol to work with it. (I know it's possible with the old, broken one. It had been setup with instructions from the HR44, which is currently unavailable.) Thanks!
