Query: a bad dvd, twice

I ordered this DVD for my son. When we received it, my son tried to watch it and it was freezing and very crackly. We returned it, expecting to get a refund, and instead got another DVD back that was just as bad. Very disappointing and aggravating! It is not our DVD player as we are able to watch other DVDs with no problem.
