Well, if a film like that is released on DVD, it should have at least a good DVD quality, and then I buy it, but if it is only in VHS quality, like so many German releases in the last 2 years, then I don't buy it.
Actually I wouldn't buy a bad DVD if the only alternative is that old VHS version we all have. Cause that is good enough to enjoy the film, and I don't need another crap release, I already have more DVDs and Blus than I can watch (and find a place for to store).
Of course good fan releases can be a problem, but that I can't change. And only waiting for a good legal release might only tax my patience.
