Sorry, I think you misunderstand. My question is: How do I make stream
0:1 (the dialog audio) the default. Right now, 0:2 (the commentary) is
the default when the video plays. I've spent a day trying various
'tricks' and nothing's worked. I've not needed to do this in the past.

SOURCE & TARGET are both MP4s.

Which of the dozens of failing ffmpeg commands that I've tried do you
want? Switching 0:1 & 0:2 worked, so I think you don't mean that
ffmpeg command. I honestly don't know how to choose among all the
commands that failed to set 0:1 as the default audio stream. Help me
out here. I can rerun some of the failing commands.
