Many thanks, as I felt like a dork asking. Meanwhile, I've done my due diligence and scoured the Interwebz for more enlightenment on all things .mpls, and have since (re)discovered things like Process Monitor (procmon); using it to find 'real' playlists; the value of having a good player like VLC in...

I held off asking this n00b question as long as I could stand it, but I give up now... Nowhere in the MakeMKV program do I see a reference to "MPLS" or "Playlists", so I haven't a clue how to make use of the suggestions in this forum – such as "00619.mpls being correct"...

Having ripped "Good Time" with the above advice (i.e. choosing 00432.mpls), I wound up with the Director version of the blu-ray title, wherein people are talking over the entire movie.

Back to the drawing board!
