Hi all...My dad would like to have some type of copyright protection for a bunch of DVD's he made for all the copies that he's about to make and send to fellow travelers. He uses Nero for burning discs.

Which software do you recommend for this, and also, can he burn the DVD's now, and apply the encryption later. He is hell bent on doing this right here right now. lol...

Thanks all...

You can do it with e.g. EncryptX http://www.gold-software.com/download3059.html

Burn now and encrypt later? How about putting a bike lock through the hole in the middle?

There is no way around first encrypting the data and then writing on the DVD. A 50$ shareware closed-source blob provides about 50$ worth of security If you want it actually secure (instead of some variant of rot13) then use PGP / GPG http://gnupg.org.

It does have a learning curve, but you can only have real security if you understand what is going on.

"Copyright" protection or "copy" protection?

Even encrypted, that doesn't stop copying.

Also, do these DVDs contain computer files, or are they meant to be played in a DVD player?

I think a message in the video saying "Do Not Copy Please" in big letters would work better. Copying encrypted DVDs is a piece of cake. Any copy protection technique is either broken already (see standard dvd encryption) or really annoying (as in loading extraneous software to enforce it, see the good ol' Sony rootkit).
