how do i prevent my dvd from being copied

[Dv8ted2]

Prot_dvd is proof that it can be done.

Uh, no...

That was broken back in 2006 if you even bothered to read.

I know most people don't use AnyDVD because it costs money.

That is a lame excuse. It is a one time charge. It is not expensive and it is continuously updated.

It sounds like you chose the wrong profession. You refuse to listen to people who know more than you. If you encrypt something, you would need to provide the decryption key on the other end for the message to be read. There is no difference. The player needs to be able to read the disc. If it can be played, the output can be copied. I would suggest that you stop trying to prop up a dying business model with ineffective methods.

THIS DISC CANNOT BE COPIED
IF YOU ATTEMPT TO COPY IT ANYWAY,
YOUR COMPUTER WILL SELF-DESTRUCT IN FIVE SECONDS

You can't "prevent" dvd copying.

You can (theoretically) "limit" the copying by having it replicated (1000 disks or more to be economically viable) and paying for "protection" to be added. For smaller lots, CDP/GLDM are licensed to use ripguard-mod for duplication.

Either way, you need to ask yourself if the added cost per disk is justified, considering the level of "protection" offered. For example, while macrovision's PR/sales folks claim that ripguard will stop approximately 85% of the people trying to rip a disk, it really only takes one successful (and subsequently distributed) rip to make the cost effectiveness of the "protection" questionable.

"Home-brew" copy protections are variants on non-compliance with the dvd-video specification (which exists to ensure that any compliant dvd will play in any compliant player), The farther your dvd is from being compliant, the more likely your customers are to encounter playback problems. Additionally, "home-brew" methods should be thoroughy researched (before being used commercially) to verify that they don't infringe existing copy protection patents. That's a can of worms you definitely can't afford to open.

Yes, it was but the prot_dvd disc can't be copied with the latest anydvd 6.3.0.0 and I should really know

Ymacrovision's PR/sales folks claim that ripguard will stop approximately 85% of the people trying to rip a disk

I believe that number, but ONLY if it also includes people who DO NOT TRY to rip discs. Maybe 25% of the popular wants to copy discs, and of those, I imagine that a third of them don't know what they're doing (and are not smart enough to find the answer online).

Again, writing THIS DISC CANNOT BE COPIED on a disc would work just as well.
I've actually done that, and it worked for 3 of the 5 people.
My "copy protection" therefore has a 60% success rate. 8)

I was just hedging my bets they'd be dumb enough to believe it. That's all CP really is anyway. A deterrent, and nothing more. To believe otherwise, you've got to be a yoga master that sniffs chocolate caves (if ya' know what I mean).

So we are back to that again?

Anydvd cracked this in 2006. You also did not consider either another batch of discs, a slower burn, or a different optical burner. You cannot make a judgment without exploring all the options. It only takes one thing to blow your arguement out of the water.

Did you consider imgburn? It could just do an isoread, isowrite...then your worthless protection is even more worthless. Many other programs can copy it as is.. Like in Nero, you do disc copy. You are not getting the picture that you should not rely on software. How many people does it take to convince you?

if the professionals with all their latest innovations can't keep us from copying their dvd's, than we can't either. What can be written can be read. it's as simple as that. All copy protection will be beaten eventually. As a matter of fact, Some people's dvd players even have trouble palying discs that are copy protected with the newest crap that macrovision and sony has. Way to go for screwing up the digital age, guys.

[videobread]

<BLADES_OF_GLORY> really impressed me. Not the movie. The Use of <>'s around the title fooled the rippers. The rippers were patched right away because it was a Hollywood movie. The <>'s were low tech sleight of hand. If a small content creator found this trick it would probably still be working today. Only Hollywood movies come to the attention of the ripping software coders who then patch the rippers. There are tricks out there within the DVD spec. If you find one, use it and keep it to yourself. Simple sleight of hand and other restructuring can not stop copying completely, but can cut it down considerably for the small content creator.

[lordsmurf]

Use of odd character's is not 100% to spec. It's illegal use of UDF or UDF/ISO. What they did was stupid, if nothing else.

[vcd4ever]

Yes, thats a very good advice and I have learned my lesson. I will never ever again post a copy protected dvd sample or post anything more about my "crap" protection here on videohelp.

just stick to VCDs, vcd4ever

[Dv8ted2]

If I were you videobread, I would focus more on making a better product. You should not wonder about Susie Q copying something after you already had the right of first sale. Your excessive worrying will be the death of you. In short, if they like your product enough, they will buy from you.

The more you try to make a non standard dvd, the more likely you are of losing business. You will eventually reach a point where the people will not be able to play the disc. That leads to pissed off customers. You ultimately have to ask yourself if the loss of business is worth it.

I am not against you or vcd4ever. I understand that you are trying to earn a living. I believe your methods are misguided. As this whole DRM era has shown us, the only people that truly get harmed are the paying customers. That makes them look for alternatives. As a security specialist, I am just trying to save you from a mistake. If you are determined to piss off paying customers, I will not stop you.

The copy-protection counterparanoia assumes that
most people or everybody WILL behave dishonestly

both incorrect and bad.

I would honestly like to know what gave the content creators the idea that everyone is a thief. I wonder how they would feel if the shoe was on the other foot. If the creator was labeled as a thief from the onset, it might change some minds in this global economy.

[lordsmurf]

In reality, the content creators seem to be the ones doing the screwing. Irony.

[ilovevcd]

Thanks ilovevcd.

Thanks for common sence about role out any possible error.

When i burn vcd @ 8X it use to jerk and play badly but burning it @ 4X it plays good. The same aply to audio discs.
So I always burn my cd and dvd at lovest speed.

Have you done some more inveigations about prot_dvd.zip or any similar protection?

There are some things i realy don't understand about this thread
* why is the common opinion that you can't do protect burned DVD
* that we are alot of people that need to protect our video productions from beeing copied.

Do you have an logical answer on the above thoughts.

[lordsmurf]

Stupid questions will not yield logical answers.
First time you asked, not a stupid question, you're excused, didn't know any better yet.
Asking when told why it won't work is inexcusable.

[ilovevcd]

Dv8ted2,

If you meen that prot_dvd.zip uses the Protectdvd protection witch was cracked by anydvd in 2006, then why can't AnyDVD 6.3.0.0 Dec 2007 copy the prot_dvd disc?

My guess:

* Linear thinking of computer types. Interesting story - I was in a masters program years ago. The professor assigned the class a mathematical problem and claimed it was impossible to solve. I was the only student to solve the problem. I used simple logic and algebra. Other's just believed that it could not be done and probably did not try. Linear thinkers don't create anything. They just copy.

* I have content to protect, but my interest in copy protection is more natural curiosity. I am a creative type and think outside the box.

[ilovevcd]

Well, thats possible I don't know. (George Lucas did what everybody thought was impossible or stupid "Star-Wars". The result was three Big movies episode 4,5,6. So keep thinking outside the box.)


I know that when you are burning CD you can burn in rawmode, thus write some very strange stuff to the disc. But trying to burn to DVD all programs and burner i tried says that it is not allowed on this media-type.

So creating any dvd-protection that require raw-mode is just out. But manipulation of an iso-image that is later burned to disc using standard iso-burn capeable programs should be possible.

The next thing to do is stoping computers from reading the structure in the IFO tables. Dealing with the iso and UDF structures may also prevent computers from understand whats on the disc.

And to tell a truth, the first thing i would try to stop is the computer, as they are used to copy the discs anyway.

What exactly you would manipulate, we cant write here for 2 reasons
1) it would not be a secret if we does
2) there would be no one to belive it, (oh, maybe we could count them on one hand)

And did you want to add something to videobread's quote or were you just trying to increase your post count? I mean really, that's a sheer stroke of genius! Let's corrupt the file structure or modify everyone's computer so it can't read the IFO of my disk...

[videobread]

For the record, That's not my quote. I'm the first two lines only.

[Dv8ted2]

Dv8ted2,

That may be a bad burn and you refuse to even try other ways of thinking. Even a halfway intelligent person will take a step back and look at all the alternatives. I am not trying to insult you. I am just attempting to get you to look at other things that may prevent the disc from being copied. I have burned many discs before that could not be copied. They were bad discs. They also stuttered during playback. Did you try multiple optical computer drives? Did you try other computers?

[Mr_Del]

I just think its funny that the pros continue to invest all this money to copy protect and then find it took no time at all for the protection to be cracked. You would think they would have learned thier lesson by now and just give it up so movie prices can come down. Imagine that, If movie costs went down there just might be less copying. Irronic though, seems the best protection is no protection.

-Del

[Nilfennasion]

Imagine that, If movie costs went down there just might be less copying.

That is the primary reason why the major studios have backed the high-def optical formats. They wanted to ram the DeCSS genie back into the bottle and shut the lid tighter. So imagine how much it burns them up when their latest iteration of BD+ or whatever gets cracked within mere hours of release.

Nelson Muntz said it best.

Thats was my fault. excuse me

[ilovevcd]

I have burned the prot_dvd to 4 different discs on 2 different burners at all possible speeds.

They all played well on several different players.

But AnyDVD 6.3.0.0 could still not copy the disc.

So i was just tinking, is it possible that the protection uesed is not Protectdvd?
