My pool instructor is producing a DVD and it needs to be encrypted to prevent copying. The movie is complete on his PC. How to encrypt? Has anyone done this? Thanks. Frank

Assuming he wants to produce a DVD that's playable in most / all normal DVD players, he's out of luck. The standard DVD encryption (CSS) was cracked almost immediately (1999) and is completely worthless now. And it has to be licensed - I don't think there's any way an individual can use it, he'd have to go thru a commercial production house. There's apparently another method that actually involves damaging the disc in a particular way but according to the article linked below even very few commercial movies use it because it's too expensive. Even the newer encryptions used for Blu-Ray have been cracked.
DVD and Blu-ray Copy Protection
Another option he might consider tho - delivering his content thru something like Udemy. If you're not familiar, it's an online education site. Probably have to edit the video a bit, at least breaking it down into short segments. I mostly use it for technology classes, but they offer everything and anyone can sign up to teach a class. Personally Udemy (and similar sites) are by far my preferred way to take classes, esp since I can watch on my PC, phone, or tablet. I really don't think DVD is a very good choice for delivering instructional content any more. He'll probably get a wider audience with some form of digital delivery.
Whatever he decides to do, I hope he succeed!
Honestly, it is almost impossible to keep things like this from being pirated. When I was an administrator, we saw Udemy videos all the time that had been downloaded, then reposted without the creators approval.
His best bet is to hope that he can make his money before somebody does so.
As for encryption, there are so many different ways to remove it, it isn't even funny. And if he does find a way, it will only slow down the hackers for a few days, possibly weeks, before someone reverse engineers it, and then posts it somewhere.
Not to be a doomsayer, but we saw this all the time. I even know someone that has the knowledge to do things like this. He does it for a company we used to work with, in an effort to keep it from happening. Hasn't worked yet....

Hi and thanks. I understand your post. Let's say someone copies and resells the material. Just the way it goes I guess. Usual discs are copied and one or two are given away. That's about as far as it goes.

Hi and thank you. Will pass this on.
And what is "vimeo".
The movie material is about 60minutes.
The movie material is about 1 hour. How can it be sold as a download (aside from a DVD). Any help is much appreciated. Thanks, Frank
