I'm losing control of my 622. At first, I thought it was the IR remote, but E* kindly sent me a replacement with no change. Essentially, the IR controller in my main room simply cannot control the 622. Sometimes, I push a button (say, channel UP or DVR ) and the receiver oftentimes ignores the command. I push again and the receiver acts as if I pressed the button multiple times. This happens with ALL buttons. This becomes unnerving when I try to step up one channel and I find myself pressing UP and DOWN buttons like a drunk, trying to home in on a particular channel. I've tried to press slowly, I've tried to press quickly. I 've pointed the remote towards or away from the receiver with no change. I have made no recent changes to the receiver or my environment. This does not seem to be an issue with the UHF controller for TV2. Does anyone have any suggestions short of a unit swap out?
