There is no better video source. The only time the unedited version of the movie has been aired was a few times on HBO in the 80s. Anyone who has a VHS of it has the best source available.
I tried cleaning up mine, but there are still artifacts from it being a second gen VHS that nothing can fix.
Hopefully he will get in touch and he'll be willing to lend his VHS to those who can really bring it to life.
