I'm pretty sure that the theatrical cut is the same as the vhs and lasedisc one.
The VHS and Laserdisc released here in the states was completely different than the theatrical version. The overall story was the same as the theatrical version but the theatrical version had a few things that the VHS and Laserdisc were missing. The scene where Hawkeye shoots Maj. Duncan Heyward when he is on the fire was a bit longer. You got to see the bullet hole in his head. The DVD version is only a few frames shorter than the VHS and Laserdisc but those were even shorter than the Theatrical Version. The end battle on the cliff side was gorier and a bit longer and in the theatrical version we actually get to see Magua eat Col. Edmund Munro's heart! It was good stuff. Mostly it was gore that was cut from the US home video releases and nothing major. But I have yet to see that version on ANY US home video release.
If you watch any US home video version of this film you can see some of the jump cuts. Especially during the end cliff battle between Chingachgook and Magua.
OK So it's not completely different but I still want the theatrical version on DVD.
