Ok, basically there are allot of posts in this forum asking how to copy protect there homemade DVDs.
What I would like to say is basically that there is no point posting this, the only DVD copy protections out there for video are industrial grade and cant simply “patch” a image file to make it protected. Even if these protections where implemented they would be useless as the Macrovision protection was defeated years ago, and the new Sony protections have been just as useless. For data protection the big SafeDisc/SecuROM/StarForce protections are around, and are pretty effective, but again, are industrial grade, and would require a contract with the company, a professional DVD factory, and for orders to be in the thousands.
As I have said in before the best method of copy protecting homemade DVDs is to put watermarks with the name of the person receiving the DVD on it. That way you can track the source of the copy, if you put somewhere on the packaging that it has been individually watermarked people will be very unlikely to still copy it.
So quite simply… “there is no practical way of copy protecting homemade DVDs, for both video and data”.
If a mod could sticky this that would be great!
