How to correctly play back Dolby Stereo movies?

[Menteith]

Thanks, this is really interesting. I wonder how many people play all these movies back wrongly - or am I the only one?

A good example is the Arrow UK blu-ray of Big Trouble in Little China. Arrow advertised that they provided the original 2.0 Stereo track on their blu-ray. I mean it literally says 2.0 in the menu and on the back cover.

Maybe I'm in the minority here, but just going from common sense I would never have geuessed to set my receiver not to "stereo", not to "DTS HD", but to "Dolby Surround"?

By the way, this example is also interesting from another perspective: The theatrical release apparently also featured a 6-track magnetic sound mix for the 70 mm prints.

What would be the "more accurate" representation of playing back this blu? Using the 2.0 channel with dolby surround, or playing back the 5.1 DTS HD mix encoded on the blu through the receiver's DTS HD mode (maybe that one is mixed based on the 70 mm track)?
