In reply to:
I believe I read somewhere that when, for instance, you use a Macro to turn on all the necessary equipment to "play a DVD", the remote will do so accurately even if some of the equipment was already turned on.
Is this true? It doesn't seem to make sense that this is possible based upon my knowledge of how the power switches work in conjunction with a remote (I thought that it would switch the component to the opposite state of on/off that it was currently in).
Make sense?
A lot of devices now have "discrete" codes. That is, a specific code to turn on the device, and one to turn off the device. These are the codes you use to get that "smart" functionality.
Without these discrete codes, you are correct, it is a toggle and you would encounter problems.
