Thanks for the responses, Petri and John.  Wow, indeed, the more I learn
about the situation the more murky it becomes!!  I thought there might
be a "simple" solution floating around, but it looks like that isn't and
can't be the case.  Not YET anyway. :)

Since the disc DOES start the correct MPLS (or perhaps series of MPLS
files, if there are warnings, logos, etc before the main title) when the
"Play" menu option is selected, then that seems to be the key and it
makes me want to track down what exactly is happening programmatically
menu-wise when the "Play" option is selected.  With the BD-J support
that's soon to be released, perhaps that will be more possible??  At the
very least I could navigate the menus with the BD-J-supporting version
of libbluray, start the main title from the menu, and use Process
Monitor as I was before to monitor for the playlist that's opening.  Is
there a rough target release date for the new BD-J supporting libbluray?
