Copy protection code incorporated into commercial CD/DVD's allows for

The copy protection prevents copies being made from copies - serial
copying.

Are you sure about that? I've seen a hybrid CD that didn't allow any
copying but most CDs can be copied perfectly for many generations, in
my experience. And most DVDs can't be copied at all.


You are correct. 'Red book' CDs do not include any form of copy
protection and can thus (from a technical, not legal, POV) be copied
endlessly.

I think "No Win" may be assuming the use of something like spdif for
copying and SCMS. My understanding is that the maker can choose from a set
of options including "no copy allowed", "one uncopyable copy allowed", and
"unrestricted chain copying allowed". IIRC there are two metadata bits for
this. But I'd need to check my documentation to know.

Not checked to see if DVDs use it for the spdif output of a DVD player. But
as you say, commercial DVDs may well use css, and this was cracked which
opens the door to unpermitted copying.

I also suspect that many serial recorders (at least pro and semi-pro) may
ignore this. As you say, using a computer to 'rip' a red book disc is
technologically easy as Philips/Sony didn't - I assume - dream when
developing CDDA that this would become easy for home users. Thus their
later promotion of SACD to try and block home users and deter pirates from
making copies.

For me the real significant distinction in all this is where Keith says he
gives/sells the CD to someone else once having made a copy *for him to keep
and use when he no longer has/owns the CD*. That last part seems to me what
would be a violation of copyright that the publishers *would* wish to stop.

I doubt any publisher would care about a disc being sold or gifted. I'd
expect you to be well within the permissions given with purchase.

I also doubt they'd care much about someone having a ripped copy of a disc
they keep, and so are copying purely for convenience and still have the CD.
Although you probably *don't* have permission for this, so rely on them not
actively objecting.

Slainte,

Jim
