But usually it's not the same people releasing various editions of the same film. They're more like completely different projects.
I actually want them to release Special Editions of a couple DVDs I already have, like the long-awaited Goodfellas.
HeinlenFan, the first Kubrick box set contained 7 DVDs- Lolita, 2001, Dr Strangelove, Barry Lyndon, Clockwork Orange, Full Metal Jacket, and the Shining, which I bought. They then re-released it with the same titles, but Barry Lyndon got a much better transfer, and I think there were a couple of issues with 2001 and Dr. Strangelove as well. They also added Eyes Wide Shut and a documentary about Kubrick. The newer 9-disc set is the one to get and it's great. I was just pissed because I bought 7 disc set first.
You mean like scrapping their LP collection in favor of CD's?
I don't think that's an accurate analogy. CDs became mainstream 30 years after LPs. New generations started their music collections with CDs, and folks could justify re-purchasing an album they bought 20 years ago. Plus, the difference between CD and LP are way greater than DVD and HD-DVD. Portability, compatibility, etc- things CDs offered that just aren't possible with records.
DVD has only been around for 6 years. Very few people are going to re-buy dozens, maybe hundreds of titles so quickly for a new format which is so similar to the older one.
