On the DVD release of season seven, FOX included the syndication print of this episode instead of the original, explaining in a disclaimer found on the episode's menu screen: "OUR FINEST HOUR originally aired on television as a one hour episode on October 9, 1978. Over time the original master materials were damaged and proved to be unworthy of DVD release. In order to provide the best visual and audio presentation possible, Fox placed the syndication version of this episode onto the DVD. This episode is now in two parts as it is in syndication."
...Viewers have the option of viewing parts one and two together, or as two separate episodes.
