All:I have had my current set up in-place for several months using the Harmony 650 as my remote of choice. Within the last couple of weeks I have noticed that the remote is having trouble communicating with the Direct TV receiver. No other devices or functions have encountered difficulties and communication to them // through them is still fine. Example: when watching TV I desire to change a channel and nothing happens. I send the same command again and the change in channel occurs. This was not a problem three weeks ago, with the receiver acting on each command flawlessly. Any ideas? I have been thinking of battery pull and reprogram of the remote but thought I would see what you folks might have to offer.Thanks to all.
