The Harmony model is Activity Based. It is also set up on your computer. The WAF comes in that all my activities are named like "Watch DVD" or "Watch TV". Behind the scenes I have set each activity up to turn on which ever device needs to be on and use the AVR for volume control. You can also access menus for each device and you can set them up however you want as well. IF something goes wrong, there is a help button that straightens out almost any misfire. About the only way for it to misfire is if you point the remote (the 880 must be pointed at the devices for direct line of sight IR) away from the devices before it has actually issued the command. This comes into play with special instructions like "Issue Dolby PLII Command" My wife says it is the best piece of equipment that we own.
