Re: Encrypt DVD-video to unknown format

On further consideration...

One thing that you probably could do is create an image or zip of this DVD-Video disc, and then add security (essentially, password protection) to release the archive. Burn this encoded image/zip to DVD-ROM (you'd need a more general-purpose burning application such as ImgBurn, Nero, or something else to burn this).

Then, provided your intended audience has the password, they could expand the archive, and as long as they have a software DVD player, play it from the DVD folder.

This scenario is outside the realm of DVD-Video authoring (which of course also means Encore), though. It requires a file archiving software program, and its security is only as strong as to whom you choose to give the password.
