Do you have a list of anime films dubbed on vhs that are not on dvd or blu ray?
Off the top of my head there is:
Outlanders.
dirty pair movies
galaxy express 999
OLD harmony gold dub for dragonball unofficially available
Then there is the harlock and queen millenia dubs from Cark Macek but the shows were cut up so badly as to be unrecognizable. It would have worked better if was able to use ssx to pad out the rest of the remaining episodes because as a broadcast requirement they needed a certain amount of episodes for a television package and they had to be dubbed.
Sci FI required a dub for Gurren Lagann and that is the only reason we didn't get a sub only release.
Most dubs are really not labors of love and are really only studio or tv network politics, policies to get a show on tv. Business that is all it is.
