The AVR is set to 6/8 channel, the choices are Direct or DVD Audio, there is not much difference, if any, between them. I set levels using Disney WOW for both options. I did set all levels in the BR itself using the spl meter. When I went through the levels using the disney disc I calibrated each component seperately, BR, DVD, Radio, Fios, on each corresponding input of the AVR. The center channel volume does increase when I tweak it but I dont want to have to do that every time I switch from movie to concert.
Thre only other audio cable connected to BR is an HDMI going to TV so that family can watch movies without AVR
