Oh, and have you guys checked out this:
http://www.worldcat.org/title/thx-1138/oclc/56520465/editions?start_edition=1&sd=desc&referer=di&se=yr&editionsView=true&fq=
It's database of all the formats and editions of THX-1138.
Another good find. Some of the entries are strange, as there's a listing for a 1995 DVD. A five inch floppy disk version too?
