Richard bought a new DVD. And he can't play it. It's "dead." Leo says that it may not be dead, it may be region encoded. If there's a different region encoding for a different market, it won't play in your DVD player. Even if it played once before, it could have become region locked after that. The next thing to check is if it's PAL instead of NTSB. If that's the case, it won't play either.
