Seems like a worthless rant to me, any movie that more than a few people would ever want is very likely out on dvd. DVD's should last for a very long time if they are handled properly.
The real problem with getting older and smaller films onto new formats isn't the new formats its the piss poor quality and lack of availability of the original source material. Before the rise of dvd there really wasn't much financial incentive to keep source material in good quality as the studios figured they'd never make anymore money once the theater runs ended. So often times the originals were tossed in some warehouse to be lost forever.
With dvd and now blu-ray and digital distribution the studios actually have financial incentive to keep their originals in good quality (or likely in some digital format backed-up in several locations). So while not much can be done about films of the past, it's a very good sign for the films of today.
