I figured as much. Never bought any of those shady fan-created releases, but for some properties they seem to be the only option. So maybe I'll cave in one day.
I'm hoping for a re-release of the 1980 Filmation animated series The New Adventures of the Lone Ranger, which has also been out of print for a long while. I see Classic TV Shop has a blu ray available but it seems to be a bootleg production.
