UPDATE:

Harmony Remote works well with the additional IR Sensors in place. Over the last year...here are my issues with the Remote/976:

Remote: It's very sensitive, so when I pick it up, whatever my finger might touch on its touch-screen face, it begins to turn on that "Activity" event if I did not consciously choose that activity. Then, because the 976 has a 12 second delay in turning on, and being able to switch functions...I get all messed up, and have to turn everything off so I can start it all over. If only the 976 Remote had worked well...but the aim is so off, and with uncontrollable volume issues...I have to suffer. Wonder if the 976 Remote has been fixed?
