Mantaray, with all due respect, you're spending too much time worrying about this stuff (from reading your various threads). Just leave it on auto and enjoy the DTS-HD Master and Dolby True HD tracks. Don't worry about PCM (Multichannel is PCM, not DTS-HD). The 905 should disply DTS-HD Master Audio when that it what is playing.
Also, if you can accept some friendy advice, you really need to visit your dealer or have someone locally explain your gear to you.
