That's honestly a strange (near marketing-esque) comment. I don't think the people here with 7.1 configs, that are complaining, care about your "goal" to "make sure the 5.1 listening experience stays true to the original 7.1 mix." They want all channels passed to their 7.1 receiver.
Hughmc, I wouldn't make any assumptions on what Sony or DTS can or can't fix/improve with the PS3.
ronny_k_at_DTS, if you can, please post something with a little more technical detail why the DTS-HD MA decoder in the PS3 is currently designed this way. I can honestly see no reason why the decoder doesn't pass the 7.1 content "as is" over 7.1 PCM, no matter what mapping it has.
