The episode "The Army-Navy Game", features a jazzier version of the opening theme.
The pilot episode's original opening title sequence was edited out of all versions in syndication. It is replaced by the standard opening title sequence used during the remainder of the series run. The original opening is only available on the OOP Columbia House and 2002 Fox Video VHS/DVD releases.
An alternate version of the theme was heard on four 1972-1973 season episodes, including "Sticky Wicket" and "The Army-Navy Game". The theme is replaced by the regular series theme in syndication, but the opening is fully intact on the DVD and VHS releases The closing sequences seen in the early network airings were edited out of most syndicated airings. They are intact in the DVD and VHS editions.
Every episode of M*A*S*H ran longer than the normal 22 minutes we see today. Each episode ran about 25 1/2 minutes, with shorter commercial breaks. The syndicated versions shown today edit out some parts of the episodes, and sometimes the "missing" footage is essential to the story. The DVD versions restore all "missing" footage and run the proper length (25 1/2 minutes).
DVD release gives viewers the option of watching episodes with or without a laugh track.
A joke version of the opening credits was created, for use on blooper reels from the series. The altered version gives the show's title as "Mish-M*A*S*H."
