Darn. I don't have either of these discs.
Looking at the Hairspray packaging online
, it is labeled DTS-HD MA 5.1. Maybe they corrected it?
Many of the folks talking about Golden Compass comment on the 7.1 sound. If the disc were really 5.1, that's how it would display either on the Oppo info screen or the AVR input status (from a bitstream). Can they be wrong? Should be easy to verify. The DTS "remapper" will not affect the displayed channel info, only the decoded audio output.
DTS has some 7 or 9 (it’s been a while since I studied up on this) standard Speaker Presentation layouts that studios can choose between, and which Bitstream decoders implementing this stuff are expected to support. Only about 3 of those ever seem to have been used.
The DTS-HD encoder has seven flavors of 7.1 and a 7.0, too. But it would be up to the studio to use the correct setting based on their source layout. Never heard of a 7.1 mix with wides, but it's wild out there.
Can view the DTS-HD Encoder user guide online at scribd: Link.
Go to p.21 in the search window to see the table.
Maybe those days are numbered, as the newer encoder tool that supports 5.1, 7.1 and DTS:X configurations has dropped all but two 7.1 configurations.
