You are using the free versions (unlicensed) of BD Copy and BD Ripper, some discs can't be processed with the free versions, although many can.

I think that statement is not relevant here. I have the paid lifetime license for BD->DVD and the two other BD movies (Boyhood & Nightcrawler) are recognized by DVDFab just fine after being inserted in BD-Drive (takes only 1 minute) in order to be copied from BD to DVD.
The failing BD disc with movie "Niet schieten" is from Belgium.
