I have a Panny XR57. Trying to teach the 880 to recognize the "SFC Music", "SFC Movie" and "SFC Off" buttons. They don't show up on the 880 "list". I trained the buttons, but when pressed I get "Remote 1" showing up on the AVR (on all 3 buttons). The 880 did recognize an "SFC" button, but doesn't seem to toggle through the "Movies" effects, and does not have an "Off".
Otherwise, once you figure out how to set all the buttons, this thing is looking very promissing!
OK, found my problem. I had the AVR remote set as "Remote 2", because I was having conflicts with my DVD Recorder. The 880 seemed to recognize most of the buttons anyway, but not the 3 in question. I reset the AVR remote to "Remote 1", and after retraining the 880, seems to work fine now.
Every now and then when I am "Listening to CD" (TV off), when I hit "Off", CD and AVR shut off, but TV turns on.... but not always. Think I'll live with it, pretty easy to go to TV and Power off... you'd think the Harmony software would be smart enough to know if there were any ON-OFF conflicts.
