copy protection for audio CD

[Laszlo Kovacs]

Does not worth anything.
IMHO any investment on copy protection
is wasted money.
What you can PLAY, you can also COPY.

The most used to copy protect a CD is that it
has a second session, in the first the normal audio
session, and a second garbaged session.
That prevents the CD to be played in computers,
since they try to read all the sessions,
and determine what to do with it.
CD players just do care only for the first session,
and play it if it’s audio.

But that’s a worthless try
(see https://www.newscientist.com/article.ns?id=dn3020),
since it’s easily defeatable by isobuster, or neros
multimounter (you can tell which session to deal with).

Another question is that copy protection limits fair use too:
a user can’t encode his music into mp3, let’s say to listen to it
while bicycling (that’s a thing I often do).
a user can’t make safety backups.
(I don’t know how this in the usa goes, but the laws in our country
allows to make safety-backup copy for MYSELF, and if I use such a
copy I must have the ORIGINAL (even in a damaged status))

Macrovision is worthless too, except that it can
prevent to copy VHS tapes from one to other, but
philips videorecorders equipped with “incredible
picture chip” regenarate syncron signals,
thus eliminating macrovision…
Funny, yes? 😉
That’s my own experience, I captured few of my sons
favourite tales to archive them on DVD.
All those VHS tapes were “protected” by macrovision :))

In addition at Conrad (an eletronic parts distributor in Europe)
you can buy a kit for about $40 called “video image enhancer” that does demacrovision too…

How much do you pay for macrovisioning your video?
If less than $40 you’re probably OK.

I apologize if I was too exasperating to you…

Thanks for your response.

It’s been several years since I had Macrovision put on any tape.

You have to take it to a tape duplicator that specializes in Macrovision, They have a special encoder to put the Macrovision copy protection on each tape. I used to duplicate 100 or more at a time and it added $.90 per tape.

“That’s my own experience, I captured few of my sons

I do believe that is correct. Macrovision was used by most of the movies distributors. Basically what it does is remove the sync and when you attempt to make a copy there is no sync. As you stated there are ways to put the sync back in, if you know what to do.

All the best, James
