40:60? Anybody with a gradeschool education knows that's the same as 2:3. Why inflate the numbers?
Anybody remember the episode where Spock spouted the impressive fiigure "One to the third power?" It's kind of like that.
As for other arguments about quality: I don't think anybody is claiming that BD isn't better than DVD. It's not entirely a question of how much better it is. It's a question of perception by the general public. Yeah, the quality is better, but is DVD Good Enough? Once again I bring up Laserdisc vs. VHS. Anybody who has seen them side-by-side -- especially if they saw them at their peak, before DVD was even a gleam in its daddy's eye -- would agree that Laserdisc quality was far superior to that of VHS, and it was a permanent medium -- no wear, no breakage, no deterioration (with a few notable exceptions). Yet adoption was poor. Why? Because most people cared less about the quality, within reason, than the convenience.
BD has less of a hill to climb. They're physically small and convenient to handle and store -- unlike Laserdisc -- and backwards-compatible with the most popular current format -- unlike Laserdisc -- and can be written to by the consumer -- unlike Laserdisc. The current prices are forbidding if you're just a casual viewer.
Eventually players will come down in price, nobody will sell DVD players any more (but the BD players will play your DVD collection), people will stop manufacturing movies on DVDs. Convenience is not the factor it was with LD because it's the same as for DVD.
... Unless the studios insist on weighing it down with DRM that makes it impossible to play the damned things. That make it easier and more convenient to download the movie via P2P, stripped of Draconian copy protection and region coding, than it is to buy the disc legally and play it as you want to. People are starting to get pissed off, guys. Cut the crap, it's getting real old. And the more customers you alienate by treating them like criminals, the fewer you'll have.
So there's this VHS tape my daughter likes to watch, that we checked out of the local library. Guess what? It's got Macrovision, which some of you will remember from the bad old days. Guess what? Doesn't play on her setup, which is an old but rather nice Mitsubishi VHS deck and a capture card in her computer. Most tapes aren't a problem, but this one wouldn't play. It wasn't the tape deck, it was the Macrovision -- the capture card couldn't hold synch.
So she played it in my room a few times, which has an old but rather nice Sony VHS deck and a regular television. But that was kind of inconvenient for me. Know what I did next?
You probably guessed it. I would have been happy checking out the tape from the library every few weeks, but noooo. Now I'm a criminal.
Know how much the studio lost on that? Zilch. Zip. Nada. But I'm sure they'll try to turn it into a statistic showing that they lost millions of dollars because of me.
I don't generally post anonymously but I think I'd better this time.
