- For the DVD release, the series was cropped slightly at the top and bottom of the frame. This was done to create a presentation that would be enhanced for viewing on widescreen television sets.
- On the 1999 UK VHS version, Episode 7 (That's All There Is) had three uses of strong language cut out by the BBFC in order to avoid getting a 15 rating and to keep the episode in line with the rest of the series at a PG rating. When the series was re-submitted in 2006 for the DVD release, the episode was passed uncut (and with a 15 rating).
- Warner Brothers remastered the entire miniseries for re-release in time for the 50th anniversary of the Apollo 11 moon landing. It was enhanced to improve picture and sound quality, more saturated, and completely true widescreen. This new version was released both in Blu-Ray format and for streaming services.
