@acuozzo I was running dual monitors and was watching the movie on the tinier MacBook Pro screen. I had no intention of using an image from the film for anything at all. But I always open both screenshots (two screenshots are saved to your desktop when you are on two monitors; again, with the shortcut "CMD+Shift+3") to be sure I delete the one I don't want (i.e. the GUI of the monitor I don't care about), in this case, I just noticed this empty region (where the DVD Player app was running) in Preview right before deleting the image.
@mosteveryoneElse yes, it must be mostly related to DMCA BS. And Apple is just being overprotective here. Since the DVD Player App is native to the Mac OS, surely it is mpy difficult to hide 'designated app[s']' windows when a user takes a screenshot.
