 Despite the fact that the HBO cable tv version is cut (actually it is not  really cut, as they show the theatrical version. What you saw on HBO is what  played in US theatres). And that the ITC/video playhouse home video version  is uncut with extra scenes, their is one scene of difference that ONLY  appears in the HBO/theatrical cable tv version. The scene where Prince Lir  goes to fight the dragon. On the home video version the dragon virtually has  no roar at all, but has sound effects for each scene he spits fire. The HBO  version uses what was in the theatres and the dragon actually had "Godzillas  roar" for the dragons voice during that small scene. Probably due to  copyrights Godzillas voice had to be removed from the home video version.  Also in another interesting note, if you listen very closely to the roar of  the "red bull" you can faintly hear Dai studios "Gamera" roar played in with  the Red Bulls regular voice to give it more emphasis. The Red bulls roar is  untouched and appears the same in both versions of the film. And finally, the  end credits on the home video tape are "window boxed" (like letterboxed,  except it is for all 4 sides, sometimes done with fullframe films). the HBO  version keeps it fullscreen instead and some of the credits are very slightly  cut off at the sides
