I just set up my Harmony One yesterday, andf I don't have a very complex system, and only have 4 activities so far, but anyway, after setting it up, of course, I checked to see if the activities went as set up, and they seem to be fine, with the exception of my 'listen to cd's' activity. The first time I tried it, it turned on my TV, as well as my HD-DVD player(used for cd's) and my AV receiver. The activity is set up to turn on the Toshiba HD-A2 and the Denon AV receiver. The Samsung HLP5063 TV isn't even in the equation, so why would it turn it on? The weird part is I tried it again thinking it's just a fluke, and it worked exactly like it should, and didn't turn on the TV. Third try.....turned the Tv on as well. Tried it again this morning.....twice in a row........worked fine. Any thoughts? Should I return it, set the activity up again, see how it goes for a while???? Thanks in advance!
