docprego, have you tried changing the input delay on the Harmony 700? below is some tips i pulled form the logitech boards. hope this helps.
If your device doesn't react to a command from the Harmony, it may be because the delay setting needs to be adjusted. By default, different devices take different amounts of time to react to a command from a remote control. To accommodate these differences in your devices, the Harmony uses several types of delays, or speed settings, to control your devices.
Power On Delay
The Power On Delay is the amount of time that a device needs to warm up before receiving another command. For instance, when you turn on a device, you may notice that the device needs a certain amount of time before it can receive another command from the remote.
Every time I turn on my system with an Activity, my TV powers on but doesn't go to the correct input. However, it does go to the correct input when switching between Activities when the TV is already on. The Help button fi xes it each time, but I don't want to use the Help button every time.
The Inter-Key Delay is the amount of time allotted for commands to be sent between button presses.
Any time I press volume up multiple times in a row for my AV Receiver, it takes a long time to increase the volume. I would like my devices to respond quicker to these presses.
The Input Delay is the amount of time that the remote takes when switching between inputs. Many devices need a certain amount of time before changing to the next input in the input list.
My TV doesn't always go to the correct input when switching between Activities and I have already verifi ed that the input list is correct.
The Inter-Device Delay is the amount of time between commands for different devices when you start an Activity. The Inter-Device Delay is also the time between the next sequence of commands that are sent to other devices within an Activity.
My DVD player doesn't always turn on when I start the Activity. I can get the DVD player to turn on by using the Help button, however I don't want to use Help every time.
The Repeats are the number of times the remote repeats a command for a device to properly respond to the command. For instance, many devices need longer or shorter command repetitions to respond properly.
Any time I press channel up, my Digital Set Top Box skips two channels at a time.
