Thanks for the support everyone. The Adventure Hour is a sweet idea that hadn't crossed my mind. I have no idea how that could be done w/o masters and/or somebody's old home videos, but a cool idea nonetheless.
I'm definitely still interested in any other ideas you might have, so keep em coming.
BTW, I currently own a PAL VHS w/ the first four eps, NTSC VHSes with eps 1, 2, 5 and 6 and an NTSC DVD of the two spliced together TV movies (all English). Getting the other sources in English shouldn't be too expensive, as Darth Venal said. The expensive/difficult part is getting all the foreign-language stuff.
I will post back here (possibly infrequently) with any progress.
Thanks again!
