And again the DVD makers/drive makers/media producers seem bent on
doing everything they can to shoot themselves in the foot. Did they
learn nothing from DVD Audio? That was the "next big thing" 10+ years
ago and never arrived because of half the stupidity we're seeing now!
It's like these companies WANT this new technology to utterly fail!

Or maybe they really are this stupid? Content protection is one
thing, but going out of your way to intentionally break something for
legitimate use is not a smart move for ANY business.

Probably too blinded by the fear that even a single hole in the
content protection scheme will reduce their potential revenue. Kinda
like how a person might clutch a few coins in both hands and refuses
to use one to pick up a few dollar bills floating pass in fear that he
will lose a coin in doing so.

It's likely what's going to happen is that the protocols will fail to
become successful, but the medium will take off. At its heart
HD-DVD/Bluray are just storage media, and eventually they're going to
come into the PC market as writeable blanks for general storage
purposes. At that point somebody is just going to use it as a
filesystem in which to fit really huge hi-res AVI files. And the next
generation of DIVX/MPEG4 players on the market will be what plays them.
For example, the new DIVX6 protocol has many of the same features as a
DVD menuing system already, including chapters, multisoundtracks,
subtitles, etc. This is a dangerous combination of technologies that
can be easily put together completely obviating the need for protocols
that the studios are planning to put out.

The AVI container format is old school :-)

(Matroska looks promising.)

They might actually want it to fail _on the PC side_, e.g. they want
these HDVD (HD or blue ray) to be able to payed only on dedicated players.
I suspect the whole mess with handling the secret keys from
different Media-makers is causing problems by video-card makers because
they just don't know what keys to put into their hardware, therefore
the last step of HDCP support - they IC holding the key, is missing.
Or maybe they really are this stupid? Content protection is one

Encryption protection of anything (specialy harcoded in ICs) is an
unusual thing which includes a lot of unusual logistics. Who should
have secret keys - IC manufacturers? OEMs? Mother Ship companies?
Considering this, the mess is quite expectable. Even though protection
is in the IC, it all boils down to a key, because having a key everybody
can program a micro or even make an ISIC which will fake the correct
response.

Remember, we are still using stupid ID-based credit cards (no
encryption or cryptographic autentication whatsoever) for a reason - it
is a complex topic. How to do it properly can be understood by few
bright designers but might hit a wall of stupidity quite fast while
moving up the food chain. Funny thing about security that there is
alwas a executive "decision making" involved, and when the executives
do not understand the technology it causes delays and confusion of the
whole thing.

Exactly.
File system is no teven needed for big media files, as long as you
have one per file.
I often do
growisofs -Z /dev/dvd=my_file.ts

More fits on a disk, no filesystem, 100% sequential so fast.
No problem filling up 20GB at all.
Sat TV here is about 2GB hour, just leave it running....
hehe
Or record a complete transponder 35Mbits/ second = 3600 x 35000000 / 8 = 15.75GB / hour.
20 GB is too small, for an evening I need 100 GB.

I'm rather certain that they do! However they seem to be making such
an effort to break things that it's not going to work on ANY side of

I'm sure that's the intention, but the efforts to break compatibility
look, to me at least, like they're prevent the use of most current TVs
as well. From my reading, unless you've got an HDTV with an HDMI
connector that supports HDCP then you're likely going to result in
reduced resolution.

I could be misinterpreting things, but I'm usually pretty up on this
kind of thing, so if I'm getting confused on what will/won't work, I'm
*SURE* that I'm not going to be the only one.
