I have a 670 and 95% of the time I watch tv, I do not use the receiver's speakers. So the receiver is off when watching tv. What's the best way to go about turning on the receiver during the rare times I need to. Do I:

1. Press Device button and turn it on that way?
2. Add a "turn on ext sound" button on the lcd screen?
3. Turn on the receiver every time watching tv and add a 'mute' option to the activity for the reciever, then create a button for the receiver's 'mute' option?

Which one is the best way to do this, or is there another way it should be done?

Thanks.
