It boggles my mind that Giles Martin had a hand mixing the 5.1 mix...6. Something's not right with the audio, and it's not only my copy. I get great echo in the rears when the "bursting rainbow" appears in between scenes. DTS & DD yield similar results. My preamp does display DTS or DD when I select them. I do hear some low level background vocals on the rears in places. For more info & other folks' comments: https://www.quadraphonicquad.com/fo...ry-Tour-Blu-Ray-October-2012/page2#post162054
