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.
