No. If you can view the content, you can copy the content.

The short answer, no. The long answer, yes, if you want to spend the money to purchase the software that can encrypt it. The only way right now to “protect” a DVD from being copied (digitally) is to purposely add bad sectors that corrupt the resulting file. Even then, it’s possible to make an analog “real-time” copy by recording it while playing. So, long story short, if someone really wants to make a copy of a DVD, there are ways around everything. For the home user, there are currently no practical means of doing this.

I don’t have a link, but I work in the film/video industry, and we sometimes get requests to make the DVDs we produce “uncopyable” by our clients… until they hear how much it costs.

Basically, the way I understand it, one way that works half the time to make a DVD uncopyable is to add extra bits that don’t get played by your DVD player that, when ripped by a computer, cause errors, and then make the resulting VIDEO_TS folders unplayable and unburnable. They do this by making the ripping software think that there was an error, which there actually was, but it’s not in a part of the disc that is essential to the disc’s playback.

I don’t know if I explained that very well. I have a rather small grasp of it myself, but like I said, this method works sometimes, and sometimes it doesn’t.
