Ok, same here. I thought there was something wrong with my queen rock montreak in blu ray. I was under the impression that it would sound better than the netflix stream option. But as soon I a poped the disc in it seemed lacking in punch. Then noticed no audio from center. I switched the audio in the blu ray to LPCM 2.9 Mbps and chose PLIIx codec on my denon 3313 for then native stereo and center worked. it sounded so much better than the dts hi res.
