I wouldn't waste my time or give the client false hopes.
DVD's and BlueRay disks are already equipped with copy
protection keys as this is an issue in the gaming world. The
first thing I encountered when looking up this topic is a list
of decryption software, a lot of it free, that people can use to
"make backups."
The system is called CSS, not to be confused with
cascading style sheets in web brousing. You might find some
application to thwart the casual weekend warier computer user,
but a determined hacker can usually crack the system if they
want to badly enough. Also, a number of these copy-protection
systems tend to bite innocent users later by failing in certain
drives or under certain conditions. If you can play it, somebody
can probably crack it.
