I am new to this, but I hope someone can help me. I have a Denon AVR 1912 hooked up to a 42-inch Panasonic Plasma and an xbox 360, with two Audioengine P4 speakers and a subwoofer. When watching movies through the xbox, the volume will change considerably when the movie switches from dialogue to music/sound effects. I have tried to turn on the dynamic volume control to fix this problem, but it hasn't noticeably changed the situation. Does anybody have any suggestions for how to solve this problem? I realize I may need to provide more information, so please let me know what you need to know in order to assist me. Thanks in advance.
