How to Copy protect my dvd's

[GSchept180]

Hi, my school and I have created several video dvd's of my school's sports games and we are trying to sell them to students in order to raise money. I dont want anyone to copy the dvd and then give it to their friends for free. I know this question has been asked before but the posts I found were from at least a year ago. My question is how can I copy protect my personal dvd's? If people can break the copy protection with something like anydvd, then great. But for the people who dont have a program that can decrypt these dvds, they wouldnt be able to copy my dvds which is my goal. So any help would be appreciated. Thanks

In short, you can't. If you want to pay licensing fees and get your discs CSS encrypted, you will also have to have them pressed prfessionally. Any protection you can put on is about as effective as printing "Please do not copy" on the disc and cover. And printing is a damn sight cheaper.

About the only realistic suggestion I've ever seen posted on here for the average Joe is physically damaging the disc. Essentially you put a a dummy 15 minute track at the end of the video then after you burn you put a small scratch on that part of the disc. That should prevent just about anything from copying it except isobuster and some of the other ripping apps where you can rip selected tracks. Not very practical though especially if you're going to be selling these discs.

I did a quick search but couldn't find the thread but if you follow the link above Gunslnger posted you'll find it there somewhere in one of the links.

Found this quite amusing:

Poster: Anyone know of a program to ADD copy protect to a homemade dvd?

Gitreel: why?

It is funny, but what is being asked: "Has anyone written a program that creates CSS DVDs?" There are a bunch a programs that have been written to decrypted DVDs, but occationally the same people hacking DVDs from netflix want protect their own personal stuff so less technically inclined people can't steal it.... Not passing judgment, or talking about anyone specific, I just find it ironic . I am not any better than anyone else in terms of rationalizing my decisions. Rationalization: How many times should I have to pay full price for the same movie. Theater, VHS, LD, DVD, DVD-Delux edition, HD-DVD. Overall I have paid over $100 for the various Blade Runner editions... but I digress.

a. CSS is a lisenced, key encryption algorythm. You can't just 'write a CSS encryption program" ecasue it has to generate legal keys for players to play them back.

b. The portion of the key that is stored on the DVD is stored in a section of the disc that cannot be written to be a DVD burner, but can only be written to when a disc is pressed.

The only options are to either pgysically damage the disc - but you also run the risk on making it unplayable - or to take the Sony approach and to add corruption into the files along the way. Similar to the physical damage option, but less visible. Again, you are pushing toward the egde of the DVD specification, and may well make an unplayable disc. Of course if you do this, no-one will want to copy it, and your problem will be solved.

Actually authoring drives and authoring media can do CSS. Not sure if you can still buy either. If you can then I am sure both are still very expensive and the drives are probably still 1X SCSI.

CSS works so well anyway right? I mean no one here has every copied a CSS protected disc?

[adam]

Right, the CSS key area is blocked on both DVD-r/w and DVD+r/w. There was a press release some time back though where the DVD+r/w consortium (whatever they are called) announced that at some time in the future they will make CSS keys writable to DVD+r/w discs. Then all you'd need is an authoring program that can add the encryption (ex: Scenarist.) But until that happens, forget about it. There's no way to accomplish this through software.

celtic_druid, authoring media cannot store CSS keys either.

I don't mean to threadjack, but I have a problem similar to the Original Poster.

I have recently gotten hold of several video dvd's of [a] school's sports games. What is the best way to distribute them? Would P2P be sufficient, or would a grass-roots "He told two friends, and so on" work better?

[guns1inger]

1. do you have the copyright holder's permission to distribute the video ?
2. do you want and open distribution model, or do you want to vet and control who it goes to ?
3. how is this even remotely similar to the original post and therefore not threadjacking ?

[celtic_druid]

The key reason for the introduction of DVD-R for General media is it contains content protection measures that make it physically impossible to make bit-for-bit copies of CSS encrypted entertainment titles.

That definatly implies that it is possible with authoring media. As I understood it authoring drives can write to the CSS part of the disc and authoring media didn't have it pre burnt or whatever.

3. how is this even remotely similar to the original post and therefore not threadjacking ?

If I didn't know S2K so well I'd say he's playing DA and intimating that he will happily distribute school sports DVDs surprisingly similar to those that the OP speaks of to anyone who can't find it within themselves to learn how to use DVDFab Decrypter, google "copy DVD" and/or bother to look in the guides section here

I dunno whether there's a lesson in that for the OP or not

This is where we need to carry little yellow cards to tag to a post. Nothing fancy, just the word "Sarcasm" will do.

GSchept180,

You can find a very similar post here, as guns1inger has pointed out:

The answer to your question is unfortunately a resounding "no way". Sorry!

To everyone else, please keep this on-topic if there is anything useful to add. Thanks!

just write"jersey girl" on the cover, and nobody will copy it

Read the whole whitepaper.

It should be noted, that CSS encryption cannot be used with either type of CDR media.

if you could make it so dvds cant be copied you could walk into, sony - universal , fox or whoever and walk out as rich as bill gates lol

[celtic_druid]

I did read that. So basically the key reason for creating general purpose media never existed? Basically that paper contradicts itself. A bit more research suggests that authoring media can indeed have a CSS key written to it, just that Pioneer's drives won't do it. At least not with available software and firmwares.

Pioneer is the one and only manufacturer of dvd-r authoring drives and the two mentioned in that white paper, the S101 and S202, are the only ones they make. Both drives are physically incapable of writing CSS keys into the lead-in portion of the disc, where they must be stored, and this was the original idea, to just make hardware incapable of adding the keys. But for added protection dvd-r general media was created and this lead-in portion is preburnt with data making it physically impossible to add the CSS keys. So in a way I guess we are both correct. It probably is possible to manufacture a drive that could add CSS keys to authoring media, but none exists and it seems unlikely that one ever will.

Now maybe I am the one that is wrong but this is what I read in every white paper and what every replication plant tells me. The CSS keys simply must be added during pressing. It is physically impossible to do it with any dvd-r authoring or general burner. What sources are you looking at that show this is possible on the S101 or S201? Or is there another dvd-r authoring drive that I don't know about?

[celtic_druid]

What I read is that the drives automatically filled the CSS portion with 0's or something to that effect. If that information is correct, then they can and do physically write to the CSS key portion of the disc. So the idea of a hacked firmware doesn't seem that unreasonable to me. Just no motivation I guess for anyone to do it, especially for anyone who would have such a drive and be willing to risk breaking it.
