Not quite. And that's part of the reason why I added "most important" to the title. For example, the DVD of Mizoguchi's film is a substandard release, but right now it's the best and most affordable option available for non-Japanese speaking viewers. Also, the initial reels of The Second Circle seem to have been mishandled by the Soviet/Russian bureaus. Sokurov has reportedly worked with the restoration team but the results aren't that great (quite sad considering it's a 1990 film). But again, right now it is the only viable option.
