There are billions of bits that get written to a DVD during burning.
Verify just confirms that the burned DVD is an exact copy of the
source. If a mis-burned bit in the middle of the movie turns a single
pixel from green to blue, you would never notice it. However, the disc
would fail still fail the Verify process. Now, if the mis-burned bit
happens in the navigation file on the disc, then the disc may fail to
play properly.

Unfortunately, even if a disc passes the verification process, that
still does not mean the disc will play properly on every DVD player. I
have one burner (due to be replaced) that will burn discs that pass
verification. But when I play the disc on a particular player that I
have, it will skip and hang up in places. However if I copy that same
"bad" disc to another disc with a different burner, it will play just
fine.
