I've just taken delivery of this thing, and I'm very happy with the way it sounds. My problem is that I don't know what volume it's set to. I like it a little louder when my wife/kids aren't there, and set differently for different movies. However I just have the volume up and down controls, so I have nio way of keeping track where it is set to. So, when I try to change it I have to do lots of adjustment to get me back to where I was before. Any ideas?
