I have an HK 210 and when watching a movie in dolby surround I have to turn the volume much higher than when watching in DD 5.1. Is this normal? I took out the spl meter and when running a setup disk the volume in the dolby surround is definitely lower, problem is if I make a change to the speaker levels it affects all dolby digital modes. I noticed this when watching moulin rouge. I had the master volume on -20 when watching the movie in DD 5.1 and when I watched the music video on disk 2 I had to turn it up to -5 to approximate the same level. Any ideas?
