The Doc and Sprocket sequences in the show were localized for each production country. In Canada, USA, and Germany, Doc was an inventor. In the UK, he was a lighthouse keeper, and in France, a chef.
The first three DVD releases from Hit! Entertainment change the title log. Instead of saying "Fraggle Rock Starring Jim Hensons Muppets", it says "JIm Hensons Fraggle Rock". The Complete First Season DVD has the original logo in every episode.
The episodes "The Terrible Tunnel" and "The Finger Of Light" both had alternate versions of the opening. However, on the complete first season DVD, all episodes (including these two) have the same opening.
