The CD-eating computer is a nice
demonstartion of how rumors start. I presume
its based on the problem with newer Mac
computers and te key2audio protection. Dur
to the lazyness of testers and pressure to
be one of the first to market, key2audio
wasn't properly tested. On some mac
computers the invalid TOC will lock up the
drive firmware. With the firmware locked,
the CD wont eject. On rebooting, the drive
reads the TOC before checking the eject
button, so the disc is stuck. Removal is a
simple procedure with a screwdriver, but
invalidates the warranty.
Audiolockbox looks like nothing special.
Just another form of protection, weak as all
the rest.
SACD is a highly propritary format. Sony has
it under a number of patents. Theres no
doupt its copy protection is secure, its
paranoid. Cant even read in a normal DVD
drive, only a Sony SACD player. But the
labels (Except those run by sony

dont want
to use something so propritary, and they are
competing with the Sony entertainment
division anyway.
DVD-audio is no more expensive to press than
a video DVD. Most of the manufactureing
expense of a CD or DVD is in the packageing
and labeling. But its not going anywhere.
Consumers dont have many DVD-audio players,
so there is no demand and so no DVD-audio
discs. Without DVD-audio discs noone will
buy players. For the format to get popular
consumers must get access to players, either
through software players on PCs which can be
very cheap or through combined DVD
audio/video players. The DVD audio spec
changes have been largely responsible for
the delay. After DeCSS was released, the
CSS2 protection system on DVD-audio was
abandoned because of a complete lack of
confidence in a CSS-like system and replaced
with the CPPM system.
