Think about it. Copying a CD-ROM means just reading it, so in order to prevent it from being copied, you need to prevent it from being read. You can do this by bending it 20 times, scratching large pieces of the gold coating off, or punching several holes into it. This would be the only imaginable copy protection, but i seriously doubt it's what you're looking for. :-) Get used to the idea that any form of ``copy protection'' is basically meaningless in the computer area, since somebody else will always find a way to work around it. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
