I recently purchased a TX-NR 545 to replace my old HT-RC 160 and need a little clarification on the listening modes. I have a 5.1 speaker configuration and chose that option during the initial setup process. My Samsung BD player's audio is set to bitstream audiophile so on BDs that include lossless audio it is being sent to the receiver directly.
My confusion is around whether or not I should choose Straight Decode or DTS/Dolby as the default listening mode when watching a movie with lossless audio. Currently I have it set to Straight Decode when receiving either a DTS or Dolby source signal, but since I have a 5.1 setup am I losing sound channels when the BD player is outputting a 7.1 DTS Master Audio track? Should I instead have the receiver set to DTS/Dolby so that it converts the 7.1 signal into a 5.1 output? I am not an audiophile by any means so please excuse me if I'm misusing some terminology. Thanks in advance.
I have googled this question a few times, but haven't found a clear response on this specific topic.
