I'm really not sure if it is available on LD, it was just me who took it for granted. It should be.
1.) 'Tarman' zombie has a deep, guttural voice that remains constant throughout the film.
2.) The "send more cops" zombie also had his voice lowered to accurately represent someone whose been dead for 100+ years.
3.) The film's score has also been altered. One song, "Dead Beat Dance," which played near the beginning of the film as we are introduced to the punk kids driving in Suicide's car, has been removed due to legal clearances. Sadly, this is not uncommon in Hollywood. Every time a movie is released on a new format, every song has to be cleared by it's respective copyright owners. The song which has replaced "Dead Beat Dance" is strangely uncredited.
4.) Frank's suicide – In the original, "Burn the Flames" played over the entire scene. The problem here was that the producers felt that Frank's death scream would be too "disturbing" for audiences, and ordered the song to be played loudly throughout. The thing is (as O'Bannon states on the commentary track), that "disturbing" is what he *liked* about that scene, and to drown out Frank's scream robbed it of it's impact. The song is still in that scene but is faded out as Frank gets into the crematorium.
5.) One other song, "Take a Walk" has been changed. This song was probably the biggest offender in terms of making the actor's dialogue very hard to hear (the producers amped up the music through the whole movie, regardless of it's affect on the performances.) Now, the song does not begin until after the punk kids run out of the UNEEDA warehouse.
6.) All of the other songs remain as they were without alteration.
7.) After Burt and the gang cut up the corpse at UNEEDA but before the bonesaw is brought out, listen to the corpse's body flopping on the floor in the background.
I think the burned in text that appears throughout the film also were removed in some releases.
