Simple answer: no.
Besides there is no point in copy protect, there is always a way to crack the code.
Little trick but not waterproof; add 10 minutes of black video at the end of your movie, burn it to DVD. Now make a little scratch on the DVD at the end of the burned data. This will give cycle redundancy failure.
Silly me - but what is "Cycle redundancy failure" and why would one want to use/do it?
That would be poor man's copy protection, Raymond.
>cycle redundancy failure
Optical discs are prone to read errors, particularly when finger prints, fluff, etc. get on the reading surface, so redundant information is added in such a way that minor errors can be corrected. If the disc is damaged sufficiently seriously, e.g. a deep scratch running around a track, the error correction system fails to correct the error, and you will be unable to read that file on a computer by normal means. Note that only the last .VOB file that was scratched would be unreadable.
I bought a cheap commercial DVD that had a serious pressing error, causing the movie to jump. Windows explorer failed to read the DVD but I did find a program (forgotten which) which made 10 attempts to read the faulty sector before carrying on. The copied movie then played perfectly (well there must have been a minor glitch where the error was, but I couldn't see it).
