The receiver allows me to chose one of the following listening modes: Dolby PLII Movie, Neural THX 7.1 or a variety of THX modes including THX Ultra2 Cinema. Is there a preferred mode for these codecs? Thanks for your help.
Since the PS3 isn't capable of bitstreaming high-resolution audio (DTS-HD MA, D-THD, DD+), select "Linear PCM" in its Settings menu. That way DD+, TrueHD & "core" DTS MA will be decoded internally by the player. If you select Bitstream, your 875 will only be decoding the DD/DTS "core" (standard) tracks instead of the high-res tracks. As for Multi-channel PCM post-processing, those are purely a matter of personal choice. The PS3 only decodes DD/DTS/D-THD as 5.1, but if you wanted to extract the rear channel from a DTS-ES Discrete track, for instance, you could apply PLIIx, Ultra2 Cinema etc on top of that to simulate the discrete nature of the original (provided, of course, you have a 6.1 or 7.1 speaker setup). Experiment with them and use whichever one sounds preferable to you... Or, you can bypass them altogether and just playback straight "Multi-ch PCM". The Onkyo 875 and PS3 threads go into more detail, so check those out.
