I notice that when I put a DVD into my Cinnamon box, Mint smoothly offers me a choice of Multimedia programs to open it with.

Plasma 5 (new Neon install) offers my file manager. Period.

This is despite the fact that I have VLC, Smplayer, Kodi and others, installed. What's up with Plasma? Is there a setting I'm missing somewhere?

Found the solution here:

Though I'm not sure why this should even be necessary in Plasma 5.8.
