So I am in an argument with someone on another forum over HD DVD vs Blu-Ray and i keep tell the dude that Sony does not have dual layer discs working yet (that is correct, right?) and he keeps denying it saying that they are releasing the BR movies on single layer discs because they make more profit on them. He wants me to somehow prove that the dual layer discs are not working yet. Perhaps I am wrong, if so let me know.Here is his last post to give you an example:

Maybe I should remind you that blu-ray and hd-dvd disks are storage devices for 1's and 0's. Its entirely up to the movie studio to use a type of compression or use single or dual layers disks. If they used single layer blu-rays its to make more profits.. not because they cannot, so unless you come up with evidences that they can't, please stop using that argument.

Blue-ray's have more space and larger numerical aperture, wich enables players to spin the disk at a lesser speed to acheive the same bandwidth.

Hd-dvd's have a ticker coating wich makes them more durable (sony's hard coating technology have yet to make its name) and are cheaper to produce.

Those are the main differences between the 2... and I will repeat. If a movie looks crappier than another.. its the fault of the studio company, not the media its stored on.

First of all, BD DOES have a name for its protection layer. It's called Durabis II.

Tell him to go to AVS. Even the BD supporters there will admit Sony has not been able to successfully mass produce BD50 yet.

The fact that the guy is spelling it "Blue-ray" should tell you he doesn't have a clue.

And, no, Sony has not yet perfected the dual layer process for Blu-ray. Heck, from the look so far of their releases they haven't perfected single-layer yet either.

As I mentioned in another thread, the last I heard was that Sony has been throwing out 9 out of every 10 DL discs produced. I would definitley call that a problem in manufacturing, NOT a studio decision to use SL.

Is it even official that BD discs are using Durabis II? I thought they went with a cheaper coating instead.

If he wants you to prove that your statement is legit, tell him to do the same with his. You'll have a hell of an easier task.

That guy doesn't have a single grasp on facts. If more people are like him, Sony will have no problem with Blu Ray.

They're not using Durabis II, but whatever they are using is surprisingly good. I had some discs pop off the hub and rattle around in their cases without getting scratched.
