I'm not advocating bootlegs here, but....
If you want the original flicks on DVD - check around on the internet for copies from Thailand. A friend of mine has them - they were mastered from the Laserdiscs. The quality is excellent, and the DVD menus and options are comparable with what you'd find on most commercially available DVDs. No, there's no 5.1 sound, or whiz bang commentary - but who needs that if what you really want is to see the original film in its original form in the best possible quality?
