    Eli,

    Make sure you have the front channels turned all the way up. Check pages 22 and 23 of your manual for instructions on how to do this.

    Also make sure you have the gain knobs on the 3200 turned all the way up. And on the back, make sure you have the switch set to “Stereo,” not “Bridge” or “Parallel.”

    Aside from that, DVDs generally have to be turned up louder than music, because they have lower levels. And, much of the time with DVDs the center channel speaker works the most.

    Regards,

    Yes, I meant the receiver’s manual. No matter, you have already found out what to do.
