I have a Toshiba HD-A2 and an Oppo 971 in the same rack, being controlled by a Harmony 520. The A2 is the new addition. I set up a new activity to watch the A2, with the same receiver and projector I was using with the 971 previously. When I send an activity-power-off signal by pressing the left-side power button, the Oppo turns on.
I can control all the other components separately with the 520 in "device" mode without toggling power in the 971, but if I use "activity" mode, I get the errant power toggle when I press the black button.
Any ideas what it is?
Is there a way to view and/or edit the list of commands directly in the 520?
Later: Never mind, I solved this myself by deleting all devices and activities, and then reprogramming them. I think the Harmony software sucks, because it doesn't allow edits to the program, or even viewing it.
