If I watch a film which has DD 2.0 sound, for example 'They Live', what is the preferred sound mode to listen use ? If I set my amp to 2 channel stereo mode I obviously only get the front two speakers. If I set the amp to surround, I presume I'll get sound out of all five speakers, but is this the amp just artificially splitting up the 2 channels, or is the surround encoding on the disk itself. Sorry if I'm not making any sense here - this is just a symptom of my ignorance. I remember my old pro logic surround decoder which would take in stereo analogue feeds from tv broadcasts and decode this into 4.0 pro logic. Does this mean that in the same manner a DD stereo signal can also be split up in a similar fashion ?
