I just recently bought the sony 350 bd player and have a Denon 1907 receiver but im baffled why it defaults to two channel and wont pick up DTS or DD for that matter. For some odd reason I have had trouble with this Denon decoding and understanding it, I have had HK's in the past with all the same decoding and it was a no brainer. It worked in the past with my Denon DVD player
