SilverWook said:It can be a blind shot in the dark, but keep checking ebay auctions for odd lots of Betamax tapes. Sometimes you can read the labels. And sometimes the seller will list what's on them.
I don't know if thrift stores bother with Beta anymore, but that used to be a good place to look several years ago.
that sounded like a good idea and, while i didn't have success per se, i did find a guy with an italian version of one of the ewoks movies -- "L' AVVENTURA DEGLI EWOKS". ha! (not sure if links to auctions are ok here, but he shouldn't be hard to locate if you're interested).
