Was listening to the DSOTM ATMOS Blu-Ray today - it has a message on the disc when you play it that explains there are problems with current 5.1 codex that exist, causing side surrounds to be played as rear surrounds once the bed layer is expanded. Also claims that the only fix is to physically re-route the speaker wires!
Perhaps PiOnkyo is not to blame after all...
I can't post a pic, because I was listening at an audio store while wrestling with whether or not to add another sub to my system. Of course, I now have to add the disc to my collection, so I will post it here when I get it.
