In fact, this MIGHT be a very bad news to (smarter?

consumers.
I happened to investigate the difference between two formats last
week; ignoring the size difference (which may come and go due to
possibility of multi-layer variants), the MAJOR difference between the
formats is the encryption.
Apparently, Blu-ray MANDATES the AACS encryption. To add AACS, you
need to set up an account with AACS (about $3K - $10K, depending on
nobody knows what), and, after this, pay AACS about $1500 for each
master disk. Currently, the state of debugging is that you need about
3 "try" masters before you get a satisfactory result. This gives the
minimum overhead price of AACS of $9K or more.
This is nothing for major releases; thus people who see HD contents
only via major movies, this overhead does not matter at all. But for
"independent" video producers, this makes releasing Blu-ray
prohibitive. Thus, a Blu-ray-only world would be skewed much more to
the side of big corporations.
[Today, to release a few thousand run costs about $3.5 per HD disk,
and $7 per disk on Blu-ray; AFAIK, this difference is due NOT to the
technical matters, but entirely to AACS fees (it is with a producer
who takes video content, and returns already printed stuff). It
won't go down due to volume economy. The printing price is
practically the same - both per layer, or per gigabyte...]
Hope this helps,
Ilya
P.S. I could not find out on which step the AACS-requirement is
enforced. Is it the player, the Sony printing facilities, or
ALL printint facilities? If somebody knows, please answer...
Thanks...
