I had a home theater system built awhile back. I have a MX-450 remote that works great. I just hooked up a desktop to my Denon receiver. I wasn't involved in the setup of the remote so I have no idea how to program it. I want to add my PC to the remote. Is it possible to turn the PC on/off with the remote? At minimum I would like to add a PC icon to my main page, so I can change the screen to my PC.
