It's two files. From what I heard, the opening scene from Makafushigi daibouken (where the Crane Hermit menaces Pilaf, Shu and Mai with Tao-paipai) wasn't dubbed in the first place, but there's still a bit missing from the beginning. Didn't look like Beta though, it looked like VHS.

"ARM" is a small group of people on my IRC network, mostly me, who do dub-over-raw, raw-over-dub, and similar reconstructions.

As for the Big Green thing - only the first 30 minutes (including commercials) were uploaded before the Daizex guys scared him straight and apparently he zotted everything he had. :(
