I just bought my Flirc, downloaded the software, and programmed my Flirc to match the keys of my Amazon Fire TV remote with my IR Directv remote. The software has accepted all of the commands. I then plug the Flirc into the Amazon Fire TV USB slot, however the Fire TV does not respond to any of the buttons pushed on my Directv remote. Am I suppose to pair the Flirc with the Amazon TV some how or is this supposed to happen automatically? Thank you for the help.
