Unless you want to press 1,000 copies forget it, it costs too much as replication is the only way to add protection. On top of that it is simply impossible to prevent someone who can use Google from copying a DVD.

This topic has been covered numerous times, as recently as a week or two ago. Doing a Search can go a long way to saving everyone a great deal of time.

That aside, Bob is 100% on the mark. I recently "ripped" a few commercial copy protected DVDs with a simple freeware program (use the clips in teaching). So the time and expense for the original producers was, in my opinion, a total and utter waste.

DVDa doesn't copy protect.... and neither do the others out there like dvdit pro.

They merely set the copy protect 'flag' on the dvd so that the dvd players knows to look for it on playback. Once you set the flag then you have to get a glass master made of the disk and send it off for replication. They add the actual copy protection at that point. As Bob says.... they won't do this for you for any less than about 1000 replicas.

So .. you've learned that you can't "copy protect' your project.

If someone *really* want to copy it .. they will.

But, at a minimum, you can insert a copyright notice and a warning that copying is against the law. It's not much but it may help to minimise the copying.

Adding copy protection to DVD's and Blu-rays doesn't help anyone, both CSS and AACS/BD+ have been broken.

But while adding these protections (and other attempts to tweak the disc format to confuse PC-drives) to the discs does not prevent copying, the lack of them does not diminish the actual copyright of the content owner either.

Take a look at Primera's PTProtect.

Nothing will protect a DVD from someone who REALLY wants to copy it and has the knowledge. But this might protect it from the casual Joe Blow copier.
