how can I create "copyrighted CDs/DVDs?".
I mean, if you try to copy official disks like WinXP, you receive a message from Nero, for example, like,
COPY FAILED - THIS IS A COPYRIGHTED CD.
I would like to know how can I create my own COPYRIGHTED CD and at least create some difficulties to copy the disk.
Any suggestions to make the CD difficult to copy are welcome.
