Then, to crib from Bogart, they were misinformed. As was I in that particular case, it seems.
It's important to note, of course, that video in any form is just an approximation of a projected film image. Not only in detail--35mm has many times the detail even of HD--but in the process itself. Having just seen Casablanca
in glorious 35mm last week, I can say that the HD version is nice (indeed, very nice), but it's not the real thing.
