I just added an AM21 to my Genie HR34-700 following the DTV instructions. My AM21 stays on (blue light) when I shut the system down. The power cords run through each other as the directions state, so why does this happen? Do I need to program my remote for the AM21? I asked this Q on the DTV technical forum and got a reply back (do not think it was a DTV employee) but they said that is just the way it goes. Everything else shuts down with one button, but there is no way to shut the AM21. Does anyone know if there is a software fix on the hprizon or a trick I can use? Thanks!
