My Sony 670D dvd/cd player is connected to my Onkyo 595. I have an S-Video hookup directly from my Sony to my Mitsubishi TV, but I have an optical connection from the Sony to the Onkyo. Now when I play a regular CD, a volume set a 25 is a little to loud; but when I am playing a DVD,(the Score) the volume is setat 50, and I am still having some trouble hearing everything. This is my very first DVD, so I am concerned that I did not set it properly. Something must be wrong. Any suggestions?
