I have the same exact problem. MEET THE BARON works just fine, but GOLD RAIDERS won’t play at all, and, yes, I did check on multiple DVD players and it didn’t work. Unfortunately, I have no idea how to fix this particular problem and I think this is the only DVD release out there, so the only way to officially have GOLD RAIDERS is through iTunes. For the record, this problem occurred about 3 years ago, but I had no idea until recently that this was actually a common problem with the DVD.
