The original run was in 1996. When The Vision of Escaflowne was released in the west in 2000 by Fox Kids, it was heavily edited and censored for a kids' audience. Afterwards, Bandai released unedited DVD sets in 2002, 2004, 2006.
The 1996, and after 2002 versions are unedited. The Fox Kids run was less than 26 episodes.
Hope this helps.
