Movies rendered by Movie Maker have a single set of stereo sound channels...
which merge the audio from the video clips and the audio added on the music
and narration track into one stereo track.

The file size of the audio portion is determined by the audio setting of the
profile... if you want a smaller audio file size portion, then lower the
audio quality. It's probably best to do it with a custom profile for your
needs.

You always have a sound track in a saved movie... when I want to put a
silent movie online and save the file space, I set the audio to use zero
kbps... the track is there but of essentially zero size.

The codecs on your system seem to differ by the tool looking at them... try
the GSpot utility and compare your results to what you see via the system
tools. I don't know why the differences, and don't explore them unless they
effect the making of movies.
