   How do big stores that sell used DVDs check the DVDs are good? - or that they even contain the film that's on the DVD's label? They can't hire a person to watch each used DVD can they?

   That is a good question. I remember that I used to occasionally rent a DVD that wouldn't play.

   they don't
   
   

   of course not it would take years to do that
   
   The CD's/DVD's are bought from reputable sources.
   any faulty discs would be discovered by the customer and a replacement would be sought from the seller.
   I have had to do that, there's never been an issue with getting a replacement

   Even new DVDs or CDs can have flaws or be incorrectly labeled. Over the years, I've bought a number of discs that had playback glitches and had to exchange them. I even bought a brand-new CD once that didn't match the case and booklet, although the label on the CD itself was correct. It turned out the music filled a gap in my collection, so I kept it and bought another copy to get what I originally intended to buy.
