Excuse my ignorance on the matter, but how does one best take advantage of a mono/stereo track on a 5.1/7.1 surround setup? Can the receiver actually properly distribute these tracks to all speakers and have it sound better than a native 5.1 track on a blu-ray?

For instance, in regards to the Temple of Doom, PDB stated "One of the best Dolby Stereo soundtracks". Does this mean it sounds really great in a stereo setup only when compared to a 5.1 track, or does it actually sound better in a surround setup as well when compared to the 5.1 track on the blu-ray?

Thank you.
