If all films are mixed to 85db then why do I have to constantly adjust the level I wish to listen at depending on the DVD I am watching? I should be able to turn on the system, have it set up to -15, or where ever it needs to be for a standard 85db, and away I go, but it never works out that way.
I have found DVD's to be much closer to an actual reference point than any music cd's, but there is still room for error.
