You can't copy protect your own DVDs! - Club CD Freaks

bcn_246 · 07-04-2005

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!

Regards,

Ben

Cool, how does one watermark their DVD?

A few ways, its up to you, all that matters is they dont know where it is so they cant remove it. For video DVD's you could put a image with there name on one of the video frames before encoding it, and saving the frame number so you can check it if you get hold of a illegal copy, or you could use IfoEdit to set the Provider ID to the persons name, or you could use a hex editor too add there name at the end of one of the vob files. I would go with the first one, as it would be very hard to spot without checking through every single video frame, and re-encoding wont remove it like it will for the other two.

Also you could try; When making a data disk, you make a small hidden file (e.g. txt file) that contains the persons name/other info. The if copies are made then all you is get a copy of the copy (

) and then you can see who made the copy in the first place.

How do you create a watermark on a personal DVD?

GenericSetup · 18-10-2007

Please see the above post which said how to do it. Basically a video editor and add a known frame to the movie.

If it's data files then use a hex editor and modify a binary file with known info you can look at later on.

You can't stop someone from copying it. All you can do is attempt to leave a trail to help you find if someone has a legit copy or not.

You need to keep track of the changes and to whom those changes were made and when given or sold to.

how does it track that the copy of a copy is sold to whom....

Someone already tested a homemade copy protection in DVD-R video based on:

CGMS (one copy is allowed) + DVD-RW CPRM media + DVD-R CPRM media?

Not really. The only "sort of" copy protection for writable DVDs is to burn your project to a DVD-RW that supports CPRM (Content Protection for Recordable Media) and burn DVD-R copies from this DVD-RW master. This seems to make copying a bit harder."

Actually, there is a sort of a workaround here.
If youy burn your master to a DVD-RW that has a built-in CPRM system, then you will find that you can copy from the RW master, but you should not be able to copy the copy.
CPRM is like the SCMS system used by MiniDisc, and basically uses a scrambling system so that only a single generation of copies can be made.

As most of new setop dvd recorders (from major brands) and dvd writers are CPRM compatible, the copy of DVD-R CPRM (with "copy of copy" not allowed) tends to be more difficult...

For the old BenQ DW-1620...

Maybe to view this DVD-R with CPRM in PC, video players may need extra plugins...:
