    Stereo electronics will sometimes "up-mix" or "down-mix" the audio to fit your component setup. It doesn't necessarily mean you're losing / gaining any audio - just that it's compressing or forcing audio into different channels.

    Ideally you would watch a movie mixed with 7.1 on a component stereo system with 7 component speakers and 1 subwoofer, since that is the setup the audio was mixed for. If you must watch it on a 5.1 then the audio would get downmixed and two channels might now be compressed into one to compensate for hte speaker loss. The problem with this is that the audio mix is now played back in a way not intended by the audio engineer who mixed it. Vice versa for 5.1 playback on a 7.1 system, so on and so forth.

    • thanks. my biggest concern was whether you actually lost the 2 extra channels completelyrandommail
