I was missing one film. The film played in Finder so I knew it was good.
Restarted, restarted PMS, refreshed library … etc.
Nada.
I put a . (dot) after the title, and before the date (of the film) though no other film has this.
Immediately showed up.
YMMD.
I suppose it’s always good/helpful to stick with the naming conventions… this will give you the best matching results anyway 
ah man, where’s the fun in that? nudge, nudge, wink, wink
