DVD Shrink: Two main movie files?



I own a movie, went to make a backup disc from the ISO, and there’s two “main movie” files. I scrolled through them and they both have end credits, suggesting they’re… both the main movie? They’re pretty similar in size, too, about 3.5GB. Checked both files out in the viewer, they both have end credits. What is this? I dunno which one to burn as the main movie?


Thread closed, as was this previous one:
