I have been reading posts with interest that involve powering on/off problems. I too have the same problem, and none of the posts I have read resolve my problems. I apologize in advance if this is redundant, but I need help!
When I initially turn on my system with my Watch DVD Activity, everything works fine. The Activity turns on my projector (power toggle), my amplifier, changes the projector to HDMI input.
I have another Activity defined where I need to keep my projector on, but change the input from HDMI to Component. When I run that activity, it powers off my projector. The projector has one power button that toggles it on and off.
I thought that as long as I use the Activity button, the remote is supposed to "know" that my projector is already on, and not try and turn it on again (which in this case turns it off). It looks to me that whenever you add a new activity and add devices to that activity, the program automatically turns each device on. So, if the device is already on, the activity toggles it off. I can't find anywhere that allows you to delete the line that turns the device on.
