I don't remember seeing this on my Denon that I just replaced. On my Marantz SR8500, when I play certain movies and engage the DD surround, it displays a quick note that says "Normalization +4". Sometimes its -2 or +3 and even had one that was -27. Is this the center channel level that I need to re-adjust for each movie? My manual doesn't mention this anywhere. I remember years ago reading something about this but I just now getting back into the Home Theater Hobbie mode again.
