Any AVR implementation of Galaxy's (combo) Octopus-Decoder|Auromatic-Upmixer
will likely be as a post-processor
. . . where it can operate on 5.1|7.1 LPCM content whether 'read straight' from BD, or decoded from DTS-HDMA or TrueHD.Regardless of whether the Red Tails BD is 5.1 LPCM or DTS-HDMA 5.1,
what really matters is whether the source
5.1 LPCM for the BD is (1
) just the 5.1 surround sound mix
) a 5.1 Auro-encoded PCM-stream carrying both the 9.1|10.1|11.1 Aurophonic and the 5.1 surround sound mixes
. Either version fed through some as-yet-unavailable Octopus-Decoder|Auromatic-Upmixer
would presumably deliver a 9.1 thru 13.1 channel mix 'to match the playback system configuration'. The real difference would be one of 'encoded+decoded as-authored 9.1|10.1|11.1 Aurophonic mix' versus "blind upmix" from a (basic) 5.1 surround sound mix . . . and if all the CE participants did their jobs correctly, then you might not be able to tell the difference unless your AVR has helpful indicator lights!

interview at Musikmesse 2012
(see Post #18
) seems to indicate release of some Octopus-Decoder|Auromatic-Upmixer
equipped devices "later this year" (relevant dialog starting 7:00).
