And don't forget the extra $$ required to buy them.
Honestly, for the most part I like Superbit releases (but I think there should be NO Edge Enhancement or ringing, something Sony has to work on. (ironically their early releases had no EE on 1.85:1 titles.) At least a lot if not all seem to have seamless layer changes.
The thing that really gets me is a barebones SB title costs substantially more than Special Editions of the same films. To me, they should be the same price, one with a lot of supplements, one with the best AV quality. It's ESPECIALLY puzzling when you see the rare SB Deluxe that costs the same as regular superbits. I can justify the highger prictag for the SB deluxes, but not for the vanilla superbits.
Yup, it's totally absurd, but CTS has managed to convince much of the DVD community there's something "special" about Superbit releases. That's why we get threads like this one or the ones that talk about the "Superbit process" or technology.
All they are is bare-bones discs, folks. The emperor has no clothes...
I like Dan's comment about Warner's discs. Superbits really are better than non-superbits, but Warner has some truly amazing DVDs out there that do in fact look better than anything that Columbia has put out - "Training Day" is a great example.
