I find myself constantly adjusting the volume of my system when watching movies with my wife. The volume is set at a certain level to hear dialogue. But when a loud scene (ocean waves, car chase, etc.) is introduced, I get that "look" from my wife that says "turn it down!" I believe Dolby Volume would be of great use to me given my wife's sensitivity to louder sounds. I would love to see it in the 997, and the mute button certainly wouldn't do the trick for me!
