You know, I was wondering the same thing...I'm in the process of getting MU-3D and, since I recently got myself a "superslim" PS3, I'm also aware I won't be able to even output Dolby TrueHD while playing the 3D disc (a PS3 caveat). The fact of the matter is I set the PS3 to linear PCM and, get this, at least on other 3D Blu-ray titles like Brave, Star Trek 2, and G.I. Joe 2, the 7.1 (D-TrueHD) channels are output as 5.1 (PCM). Something tells me something is lost in the process, but I'm no expert and, when closely listening to it, it could all be just me subjectively "hearing a difference." I mean, why not LPCM 7.1
To go even further OT ranting about my PS3's underwhelming performance issues, last night I played my old Extended Edition DVD (not Blu-ray) of Part 1 of The Fellowship Of The Ring just to try out the DTS-ES 6.1 track on the PS3 and ran into a new set of difficulties: PS3 bitstream won't even output that! I realize DTS-ES 6.1 is a fancy codec available only in a very short list of very select titles, but this is a DVD for crying out loud! You'd think it gives you maybe DTS 5.1, right? Think again! It outputs PCM 2.0! After struggling (and cursing
!) a bit, I found the solution was to set the PS3 to output linear PCM and, for some unbeknownst (to everyone
???) reason, the PS3 now reads on screen it's outputting DTS-ES 6.1!!! But, NOW the problem is that my ONKYO receiver reads PCM 7.1 input, and so I'm able to get the same output. This is a 2011 model that used to have a Sony DVD player hooked up to it via digital-coaxial (not an HDMI upconverting model) and which acknowledged being fed DTS-ES 6.1 and output it as DTS-ES 7.1. Furthermore, the very same LOTR DVDs include DD EX 5.1 (a DVD codec a bit more common--Star Wars saga, most PIXAR films, a few Harry Potter ones, Charlie And The Chocolate Factory, etc) and with that setup I got DD EX 6.1
input, DD EX 7.1 output. All the while the receiver lighted everything nicely and accordingly on its display and sounded great to me. So, I also tried the DD EX 5.1 option last night on the PS3, and what I got was, via bitstream, DD 5.1 (no "EX" to be found, less even "6.1") output from the PS3, and which the receiver read as DD 5.1 input and output as DD EX 7.1; via linear PCM, I got PCM MultiCh output from the PS3, and which the receiver read as being input PCM 5.1 and output it as PCM 7.1.
Mind-boggling why a more sophisticated Sony device which is hailed as one of the best multi-format players ("It only does everything"--NOT!) can't get these things right, huh? Anyway, I found that linear PCM output from the PS3 (on-screen showing DTS-ES 6.1) and PCM 7.1 input/output on the receiver was by far the best option--there's even a considerably higher kbps reading this way, around 755 kbps vs 400-and-something! The receiver won't display anything fancy, but I truly believe, after listening to about an hour of Fellowship, it sounded AWESOME and "as if you sent it the original bitstream." Took a while, but I think I got it right this time, and I'm ready to revisit the whole Lord Of The Rings Extended Ed DVD series--it even put a smile back on my face and made me happy for owning a treasured set and not yet falling for the Blu-ray upgrade (I don't think I ever will, as that DVD Box Set is the most handsome item in my movie collection--unless they were ever to bring out a 3D-conversion, that is
!). Moreso on the plus side, it looks a lot better HDMI-upconverted by the PS3!
I guess there'll always be a "workaround" to every problem, but the fact remains it's exactly that: a problem. Time to get a PS4 and see if that'll take care of "doing everything"? Count me out!
Thanks for letting me vent!
