 I'd like to read up on DVD technology too but I've
 not been able
 to locate much (I'd like to read the various
 standards that
 detail the physical layer and so on, not some
 non-technical
 overview - I can find plenty of those.)

Yeah, me three.
I'd like to know what the difference is between
a writable (write/rewrite) CD/DVD and
ordinary ones.
How do you "write-protect" a CD/DVD??
This would be useful knowledge, especially
when I get a DVD-recorder (sometime this
year).
