Query: Sound problems with the DVDs

The low rating is for the sound quality on the DVDs, not the movies (I give 5 stars to those). The dialog is so quite that I can't hear it. It is really bad in Casablanca where I had to change the volumn from 14 in the music seans to 25 for dialog, and still had trouble hearing it.No one else has mentioned this in a review, so maybe I just got a bad set and should return it for a replacement.
