We purchased 3 DVD's, but two of the 3 dvd's didn't work in our dvd players. We bought them for my father in-law to take home with him, but when he tried to watch them only 1 of the 3 worked. By the time we came back from vacation it was too late to return them. The dvd's had 2 different global regions of play.
