Also, according to this: http://www.youtube.com/watch?v=xWG4LU-8pn4
someone has a much better source for Quest for the Mighty Sword than I do.

Asaki, I'm the one who posted that video on YouTube. The source was a 700mb VHS-rip I got off an ed2k network ages ago. If you'd like a copy, send me a PM and we'll work out a trade or something. Having said that, there are other clips from the film on YouTube that are taped off a cable TV broadcast that probably are even better if it was taped to DVD-R.
