Ok, so I get what you are saying about the 5.1 output. Chances are, only 1% of the users would actually use it. To work properly, you would need to set crossovers, set line level, and set distances. Ideally you would have a mic that connected to the TV for these novices to autosetup. This would be costly to set up and can be done easily with a cheap reciever. None of these settings are required for stereo pre-outs. Most of these folks wouldn't even set that up properly.
Ok, i guess I will stick to harmony 890s. The main problem I have with my other remotes is that folks don't point them at the TV long enough for everything to switch properly. RF solves that problem. Another thing I can do is set up my reciever to route all the signals over a single HDMI cable to the TV. This would eliminate having the change any TV inputs and now all you need is to power up the TV. Anytime I can eliminate a complexity I'm happy and they can learn the system better. Sorry, to ninja this thread.
