I recently switched from D* to E* and I'm glad I did. However, my vip622, which controls both my den and bedroom tv, does not send the signal reliably to the bedroom (tv2). I have to hit the control buttons several times and move the remote to all different positons. It gets frustrating that I can't find a good, single position where a simple one click command will work. Any ideas on how to improve this? I have already replaced batteries twice so I know they are fresh and I have positioned the antenna on the back of the 622 in every direction I can. The bedroom is about 40 feet from the 622 and goes through two walls - could that be it?
