What you have set up on your Harmony One is what I am trying to achieve. It appears your 976 does not default to the "last input used" when it gets turned on again. I have my Amazon FireTV connected as the "Media" input into my 976, and have "Watch FireTV" as one of my activities on the Harmony One. However, when I turn the system on by hitting the "Watch FireTV" activity button on my Harmony One, the 976 turns on to whatever input was used the last time we had it on. I have to hit "Watch FireTV" again to get the 976 to switch inputs. It works the same for any of the five other activities I also have set up on the Harmony One. Since you have made it work, I'll try again at programming my Harmony, but I thought I had already tried everything.
