"Fellowship" DVD mistakes

I borrowed my brother’s “Fellowship of the Ring” DVD, and on the second disc of the extended version the labels onscreen are wrong. The cast is talking, but the computer-generated text claims the speakers are from the production team. Not only that, but the fourth disc is not the second disc of the extras, but a repeat of the second disc of the movie.

How do I tell if a four disc set is the printing with the problems? I assume they eventually fixed it.
