I followed the instructions that were packed with the Flirc.............oh, wait.............there were none. Anyway, I visited YouTube to find the instructions uploaded by Flirc or Jason. Again, there were none. I read the instructions concerning pairing (teaching) distance on the Flirc website - umm, there were none. And since the Flirc is advertised to work with ANY IR Remote, why is using the MS Media Center Extender profile not acceptable ? Both your statements make no sense to me. OK, I watched a couple consumer YouTube videos and they showed the pairing process. I did exactly as shown. Here are the videos used for reference: https://www.youtube.com/watch?v=ThjOmpwKgh8
