how do i protect my DVD's?

[cypher007]

i would like to add copy protection to my own DVD's, which i have authored. are there any programs to do this?

I believe you have to purchase a license to do this. You can't add CSS to discs without being an authorized content provider. Also, consumer-level DVD burners are not capable of recording the CSS keys -- you'd have to purchase an authoring drive, which costs well into 4 figures.

what about cd protection systems?

im not looking to css them, just stop your avarage joe with a copy of nero from doing a disc to disc. i wondered if any of the free cd protection systems would help. the other thing ive found is if i burn using udf only i cant read the disc in my dvd-rom anymore, but it plays in a standalone, why?, could i use this approach? also is there a way of adding macrovision?

There's nothing you can do at the consumer level to make a DVD or CD uncopyable, without munging up your firmware, which I wouldn't recommend.

Macrovision is just a flag that's set on the disc, that tells the player to apply it to the analog outputs. Since tools like IFOEdit can reset this flag, it stands to reason that you could do the opposite, although I don't have any experience with that myself.

Why on earth would you want to copy protect your stuff????
