By Harmony we were able to reduce to a remote control 4. Play software on the PC and be led. Worked out well for me. Philips TV 7000, Receiver of Technisat, BD player from Samsung, Philips Soundbar are now controlled through action buttons. However, I have several actions also need to delete 2-3 times and reprogram. Why some devices were turned on that I had not chosen has not been revealed to me. Now it works, and we're glad to have space on the coffee table.
