Alternate versions

Many of the syndicated episodes from the American DVD sets are further edited to remove music and songs which were claimed too expensive to license for home video. In a few cases, this results in episodes which run for less than 20 minutes! The European sets released by Warner does not suffer from these problems, except for: season one's "For your eyes only" lacks one scene due to music licensing issues. For season two's "Somewhere over the Rerun" the shorter syndicated version was used.

For syndication the episodes were cut down to 21 minutes. These edited versions were used for the US DVD release, while the European sets featured the 24 minute full length episodes.
