There have been several different edits of the series: Some, but not all, American PBS stations recut the series into seven 30-minute episodes when they began transmitting the episodes nearly two years later, in December 1982. Other PBS stations re-edited the programme into TV movies, broadcasting more than one episode at a time without interruption. The UK videotape release was on two cassettes, each consisting of three episodes edited to run together and also adding some previously unseen material. The soundtrack was remixed into stereo. The North American VHS tape released by CBS/Fox Video included this material on a single video cassette. The DVD edition claims to be the final and definitive version of the six TV episodes.
