Checked my VHS and there is approximately 15 seconds cut from the scene with Greta, and another 10 or so from Dan's scene. My set is the US Box set, so will have to check the Aussie DVD release to see if it has the same edits, which were apparently originally there to achieve a American R rating...
The cuts to Dan's demise are mainly insert shots of tubes and pipes snaking into his skin and the first stage as the skin ripps from his face. At least no sense of the scene is lost with these.
I've never actually liked the Greta scene, it always felt a little clumsy and forced. Still for an expensive box set, the edits are annoying. Glad I got it cheap.
