I find that audio levels on DVDs seem to vary significantly. I know that Dolby Digital includes a feature called Dialog Normalization. This is supposed to provide an offset which should result in correct playback levels on all DD tracks by setting the same volume level on your processor or receiver. However, this doesn't always seem to be true. DTS tracks do not have the DialNorm feature but usually play back at 5 to 6db louder than DD tracks. Another problem is that even when setting playback for a normal dialog level, opening logos and menu audio levels are sometimes excessively loud, especially MGM DVDs. My approach to the problem is to place a small typed label inside each DVD case indicating the correct level setting for that film. However, that doesn't solve the problem of the opening logos and menus. Is anybody else bugged by this problem? I wonder if the studios ever listen to their DVDs.
