It's a fact that a good number of people, including myself, have experienced that Something Weird Video's dvd-r releases do indeed "rot", i.e. they start to freeze, skip, and eventually stop working. However, I'm 99% sure this is due to the glue on the paper labels that SWV stick on the discs. I've had SWV dvd-r's that started to go bad after 6 months!
I think it's a brilliant idea that MM are willing to make their out-of-print films available as print-on-demand dvd-r's for those fans who can't find them/don't have the money or wish to fork over steep collector's prices for rare OOP editions.
I don't see the problem that some serious collectors might have with it. If you're a serious collector it shouldn't be a problem that they exist on dvd-r. Is it a problem to the VHS collector that a film exists on dvd or bluray? Of course not! All you have to do is track down the original dvd version! Besides, even if MM were
to skip the dvd-r format and instread print up a batch of new dvd's, how would that benefit the collection of the serious collector? It would still be a second printing!
A reprint!! No good for the anal, serious collector anyway. He wants the 1st print edition.
