Oops.  That's what I get with copy and paste.

Like I said, I don't have any files with multiple titles to try it
with.  I would have thought that both programs would list them in the
order they appear on the DVD, but it sounds like maybe not.  You could
use "makemkvcon info iso:${INFILE}".  With the output from that, you
could grep out a list of titles with times and sort it to find the
longest.  I don't really have the time right now to figure that out,
but maybe this weekend.
