Just got a new HR44 Genie whole home DVR. The problem is that the DVR stops responding to the remote. The remote is new with new batteries. The green light continues to flash and controls the tv fine. I have found if you press the guide button on the front of the DVR, all of the remote button presses will play all at once. After this, the DVR responds again to the remote. Dtv has replaced the DVR once and the new one behaves exactly the same way as the old one. Am I missing something?
