 When Series Three was first released on BBC Video, the episode Marooned  earned the first half of the series a BBFC 15 rating, due to a conversation  about Lister losing his virginity on a golf course aged 12. Upon its DVD  release over a decade later, the BBC wanted all the DVDs to have the same  BBFC 12 rating, but BBFC regulations meant the episode couldnt be  resubmitted and reissued in its present form. As a result, the DVD producers  tacked a ten second Starbug model shot onto the end of the credits, and  submitted this as a "new" version, which received a 12 rating, and released  this version on DVD.
