Compared are the cut UK-VHS by Universal (First Edition, identical to the CIC VHS) and the uncut R-Rated-VHS by Universal.
Difference: 1 scene with a length of 26 seconds.
Brian De Palma's action classic was cut for the VHS release by CIC and so was the First Edition by Universal. Both versions lacks one scene. The theatrical version in the UK was equally cut. Any other edition in the UK is uncut.
Manny is siting in his car, hitting on a chick. But she's not interested anymore, breaks free and keeps walking. Manny is upset about it. He focuses on the building again. Inside the building, Hector tells Tony that the leg was going to be the next body part that gets sawn off and moves the chainsaw near Angel's leg. Tony, still being threatened with a gun by one of the henchmen, can't do anything to avoid it. Blood splatters into his direction while the sound of the chainsaw is still audible in the background.
