I did put together an extended edit. It has ALL the additional footage found in the television version but without the edits to language & violence.
My extended edit is in fullscreen. Having to crop the (widescreen 4:3) deleted scenes (from the DVD release) and reframe (and sometimes zoom in) each individual shot, has resulted in a great loss in resolution. My extended edit has a very soft image. I’ve never shared it as the picture quality isn’t very good.
I don’t know if there’s an edit out there that has EVERYTHING back in. It wouldn’t surprise me, JAWS is a VERY popular film.
