Right now I am running the Denon DVD-1800BD blu ray player and connecting it to the Onkyo TX-NR905 using an hdmi cable. When ever I run a blu ray dvd (like X-Men:The Last Stand), the Onkyo displays something thats not true 7.1. On the left side of the 905's display where there are the little boxes, the boxes that are lit up are FL, FC, FR, SR, SL, LFE, and SB but the SB box is in the back center.
Does this mean that the back left and right are matrix from one source? How can I get it so the display lights up the SBL and SBR instead of having only one box in the back center?
