Did you set the proper level for each speaker and subwoofer ? You have to do it manually for each mode on your receiver. How about delay (front/rear)? Is your sub switch to "auto", "on" or "off" position ? Digital out from DVD is enough if you don't wanna use Zone Two ( or even 3) for another room or outside. For that you have to use analog out also (and possibly speaker switch). BTW, I think that you are playing funny game with us.
