how do i prevent my dvd from being copied

[videobread]

My suspicion is that the file is some type of what I think of as a video CD, it is structured like a VCD, just somehow burnt onto a DVD. Is there a menu system? Probably not. The DVD just plays in newer players would be my guess. I have assumed all along that the media is fine and in no way an issue. Just my guess.

[Ai Haibara]

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?

Technically, AnyDVD is a driver, one that's supposed to intercept and disable certain things. It doesn't make copies.

What program are you using to attempt to make copies?

You know what happens when you assume.

I had hoped that you would have dropped your anti-customer propaganda by now. I guess some people just have to learn the hard way. When you go out of business, it will be your own undoing. For the 50,000,000,000th time, if it can be played, it can somehow be copied. You should focus on trying to make a better product rather than assume that everyone is a crook.

Hey DV8ted. Why don't you start a thread listing all the things you can't do. I sure it would be lengthy.

One more post in this thread, not related to how (not why) to protect a Video DVD will render instant warning.

No dear videobread, it has a normal DVD structure and also a DVD-menu

[ilovevcd]

In order to create an effective copy protection i belive that there is a few things to think of.

1) Stopping image ripping software like ISO Buster, Ultra Iso, Nero Burning rom
etc from exctracting data off the disc.

2) Preventing a filebased system (computers) to access or copy the files on the disc.

3) Stop rippers or shinkers from ripping the IFO structure of the disc.

If one is able to cover this tree things i think it should bee dam hard to duplicating
the disc. Stopping it from beeing copied at all i think is stupid to belive.

But if all those One Button programs can't copy it, a lot is won.

[ilovevcd]

Hmm. tried to copy the prot_dvd with the newest version of isobuster, but yet another failure. But this is what i found.







Can any one explain how 2 titles are missing in IFO mode, but availible in iso and udf.
But there all videofiles are zero bytes long.

[lordsmurf]

One quick guess is the IFO files don't contain DVD-Video compliant data.
That happens when you screw up an IFO.

That would mean DVD players may or may not play those titles either.

All players that i tried the dvd on says that the movie is title 3. Acroding to isobuster, there is no title 2 or 3 in the ifo structure.

By the way, all copyprotection violates the dvd-spec.
This aplies to both burned and pressed DVD.

And by violating the DVD-spec, no one can asure 100% compability on all players.

No, CSS is the original (and within specs) DVD copy protection.

You would also need to add Vobblanker to the list. It could also rip discs.

Dv8ted2,

Yeep, comlpains over IFO structure error.
When continue with deepscan it just quit
Yet, no program i tried could copy this disc

Dude!!!!!!!!!! Brother!!!!!!!!!!!

I have SOOOOOOOOOOOOOOOo been biting my tongue for the last 3 pages of this ridiculous thread!!!!!!!


I can't believe no one has even come up with a good argument for this crap yet!!!!!!!!

I'm thinking someone, or two someone's need to get a room..... 8)
Cause they are SOOOOO in love with hearing themselves..... or seeing themselves (their own writing's)

Anyone can make some files in the dvd file structure that won't rip... it's called a "non compliant" dvd structure!!!!!!!

Anyone can make corrupted files that won't rip from a dvd.....

Now take these files from this so called "prot_dvd.iso", incoperate them into an actual compliant dvd video, get them to play on 100%... hell.... 50% of standalone dvd players, and yet can't be ripped even though they play fine...
and you would not be here talking crap like you had a clue....
You would be on some beach in maui with a bunch of nekked women catering to your every whim for the rest of your live's

Yeah... you burn this "prot_dvd.iso" to a dvd-r".... and it wont rip... ooooooh.... gee... it must be some magical all mighty copy protection that can not in any way shape or form be beat..... huh.... there is nothing there!!!!!!!!

See this line again...

[Supreme2k]

To be fair, mats, I was trying to decide if I could join in on the technical aspect of this thread, but got (more than) a little confounded by what/how it was being said. While lordsmurf may have been a bit harsh (did I just say that?), sometimes people need to be reminded that they are on a technical board and that clear and coherent posts are essential. Now, if it is indeed a language barrier, no harm - no foul.

I guess what I came here to say has pretty much been said. Most of these new "protections" actually push the discs out of spec. Kind of like saying that I can prevent my car from being stolen by putting triangular wheels on it. Or prevent my food from being eaten by poisoning it.

[lordsmurf]

I tried homebrew copy protection methods about 6-7 years ago, before most people even knew DVD burning was possible. In many cases, they were still going through puberty and living in mommy/daddy's house. I don't want to be harsh, but these YD's need to take the fingers off the keyboards (quit typing BS) and read what they're being told.

It's really easy to deviate from the DVD-Video spec. With little effort, you can go into an IFO or VOB file and totally botch it. Same goes for messy burning methods.

In some cases, you can do something stupid that works on your one player, maybe even 1-2 others. These are the same people who, several years later, after buying a new DVD player, come into a forum with the "my data disappeared" and "my DVDs must've gone bad because they don't play anymore" posts. No moron, you made a NON-DVD-VIDEO disc, and now you're paying for it. It happens quite often with KVCD, KDVD and other non-compliant crap.

Yeah, I'm getting a little rude and a little harsh these days, because people suddenly don't seem to want to listen to reason. Most recent posts I read can be summed up in the following key statements:
- Screwing up your IFO files or other aspects of the disc is not copy protection.
- Your data did not "disappear". Something else happened, you're just not willing to do proper diagnosis. You'll probably have many more problems until you find the real cause.
- Quit buying Memorex and no-name crap. Such media (often CMC and Ritek) is a gamble, often a losing one. And it does not matter what burner or firmware you use, the media is unreliable.
- Panasonic does not, and never has, made good DVD recorders (referring to image quality). Want a good image quality? Buy pretty much anything else. Toshiba, JVC and the newest RCA and Philips are suggested.

Live with it, those are the facts. You can't change them any more than I can (and I don't necessarily like any of it either).

Then you know how I feel when people buy a new, larger television and whine that it looks worse than their old 51cm CRT when they did not take the precious time to calibrate it properly, have not taken the time to work out how to get it displaying at its full resolution, are playing a disc that crams three hours of material into 4.35GB, or in many cases a combination, if not all of the above.

/Mats

Yes. CSS was the final step in developing DVD for release to the general public. DVD was technically ready for release in 1994. The movie industry did not wish to release DVD to the public without an anti-copy mechanism that was fool proof and held up the release until CSS was perfected. CSS is an integeral part of the DVD format. It was anticipated that CSS would take between 8 and 15 years to be broken...and by then they would be ready to release a new and much superior format, so no worries. The Linux crowd spoiled the party for them and now the rush is on to get a new format with a big, bad copy protection scheme...if only the public would start buying the stuff.

Once CSS was cracked, DVD was wide open. The only way to protect your copyright material from missuse is to do what the major studios do...be litigous. Sue, sue and sue. The music industry has been effective with this approach (Napster and others), but containment has been a challenge. Every judgement won provides a deterent to those who may seek to infringe upon your material.

I'm uncertain if the OP was asking about original material or material that has been obtained. Either way, since CSS has been broken DVD's can be copied. Tweeks can be, and have been, employed to slow the process and deter those who are not persistant, but DVD's basically now have the same protection as a 3.5" floppy disc, and no one can copy my 3.5" floppy discs...because I dont have any.

From a technical point of view, it is always encouraging to see people enthusiastically debate as to whether or not something can be done. If someone did perfect a way of protecting DVD (or any other) digital media, it would be prudent to immediately apply for patent rights and protect their interests as it would be a very valuable technology.

In some cases, very definitely. In others it's not so black and white. However there are certainly enough documented cases of affected playback due to the methods now employed to be able to safely say that it does produce an inferior product and reduced viewing experience for some consumers. And for all their efforts and 'screw the customer' approach, it hasn't slowed down anyone but the dim-witted.

Yes. Just as some infamous Sony audio CD's aren't allowed to carry the Audio CD logo, many new Video DVD releases shouldn't be allowed to use the Video DVD logo.

Yes and no. ARccOS tinkered with ECC on discs. It was supposed to be within the spec, but some were so overly draconian that they did fall outside the spec. That's one reason Sony officially discontinued ARccOS, and why they've had to replace/recall certain discs. They were not corrupting the DVD files themselves, like IFO and VOB, but rather the structure of the disc in regards to error correction.

RipGuard from Macrovision also dabbles in this sort of "protection" and many players are known to halt on title protected with it. This one does apparently directly violate the specs.

This is why CSS tends to be the one and only protection method used. It might be broken easily, and long ago, but it still keeps most people from making copies. From my research, I'd say the % of people wanting to copy discs (in the USA, at least) is less than 20% (about 2 in every 10 people). It's a foolish choice to infect 100% of people with bad discs, only to stop 20% who may not even want to copy your title.

You can always rip these discs, or get a replacement. Are you willing to mess up homemade content with a "protection" method that may not be playable on your next player, or on your customer's machine? You'd be a damned fool to do it.

[redwudz]

I recall the same type of problems when Macrovision came out on VHS tapes. I rented tapes that wouldn't play back because I used a video monitor instead of a TV set. After returning several tapes, the store started to take those off the shelf due to complaints from customers.

Then a few months later, the manufacturers apparently lowered the 'level' of protection to a level that gave them less protection, but would play back on most monitors and all TVs. If the consumer complains enough, the video rental stores and the manufactures will have to listen or lose customers and money.

Yet the DVDs, even though "wide open" as they are, ARE STILL SELLING LIKE HOT CAKES, aren't they?
And what does it tell us? That the copyprotection is completely unneccessary, because if people like the product they will BUY IT, and if they don't like it - they won't buy it, or even steal it for free from the web, I proved this point long time ago with some 'big movies' that flopped in theaters and on DVDs because they were just what they were - bad movies, bad product no one wanted even for free.
Studios were complaining about i.e. "Poseidon " movie few years back not doing well in theaters because it was on the web, but I remember posting here that even the "pirates" were basically ignoring it too while i.e. Star Wars last installment - widely available and downloaded by half the world before even it was in theaters - still sold well in theaters and on DVDs, and Im sure it would still sell well without CSS and other copyprotections on the discs, simply because people wanted to buy it.

This thread is so pointless, and if people don't understand relation between one thing and another by now - they never will
I don't know why am I even posting here lol

[ilovevcd]

Got this far in the tread it seems evident that protection on burned dvd is possible.

Acording to my isobuster dump on prot_dvd all vob files are zero bytes long, and a file that is zero byte long can't be copied.

Copy the files to the hard disk is not working, you can't copy empty files.

This apears to be an effective way to prevent file copy.

How do you make a file zero byte long on dvd?
