interactive dvd disc pin number

[dany_boy]

hello all,
i have a dvd movie and on the title screen it has a 3 digit pin number menu which u must put the correct pin number in to view the film.
if you enter the wrong pin it wont play!!!
I have never come across this before? the idea is that you have to ring a premium phone line to get the pin number to enter on the screen and then view the movie.

what i would like to know is = is there a way to bypass the pin number and watch the movie?
i have ripped the dvd and extracted the content with vobedit and played the movie perfectly - but i would like to play the movie on the original disc without phoning the phone line for the pin number.
how does it work??

Thanks,
Dan.

You might be able to determine the pin no using PGCEdit and tracking back through the code logic. Essentially it will be a simple series of menus. Enter the right number and you get the next page. Enter the wrong number and you stop there. The number will be fixed, so once you work it out you should be OK for then on.

A guy on the forums here in the past proposed a similar sort of thing to serve as a kind of copy protection on a homemade DVD, but I've never heard of anyone actually doing it except for the guy who talked about it. I'm guessing that this "premium phone line" involves some, ahem, "adult entertainment" and associated charges, so I can understand your reluctance to call it.

guns1inger's suggestion may indeed work, but it's quite an involved operation to do this for a newbie. I think there are some guides on PGCEdit, so you might be able to figure out how to do this eventually. I'd say you might just look on a P2P site to see if someone has already made this available and maybe they have included the pin number along with the movie. That's not real likely to have happened, but it would sure be a lot less work than what you're going to have to do to use PGCEdit. Finally, you could just try all of the numbers between 000 and 999 and eventually you'll hit it.

I do have one more thought. If you still have the disc, it might be possible using something like DVDDecrypter to rip the disc in IFO mode and extract just the movie. You'd have to re-author it as a DVD, but it would be the movie minus any menu stuff and there's a chance that you could watch it without having to enter any pin number.

[Noahtuck]

I was thinking, if you go through the trouble to rip it you could use VobBlanker to get rid of those first menus and jump straight to the main menu and just reburn, no need to go through the hassle of reauthoring.

@ jman98
I think i remember that thread, or one along those lines because i remember making a dvd with that code locked menu and making one in DLP to see how to make it harder to get around, but nothing gets around ripping it 8)

Excellent, cheers mate - i will give PGCEdit a whirl.

Cheers for your help but i've already done that....in my first post i said that i had ripped the dvd and used vobedit to extract the video and audio and watched it that way, but thats the easy way of watching it and i'm not really interested in the film to be honest.

The challenge is the pin number menu - i've never seen anything like it and getting around it without phoning the premium number is the object.
cheers anyway.

Hello
The locked pin and play disc is an adult disc given away with an adult magazine - You get one clip free and you buy the ones you want to watch using a premium rate number - you must have one of the older disc's because the new ones are copy proof - The only way is to work out the pin number - PGedit will not help nor any other ifo edit program nor ripping program such as dvdshrink or dvd decrypter - The older disc's were locked using a layered menu structure but the new ones are being done with a unique to disc algorythm

[videopoo]

PGedit will not help nor any other ifo edit program nor ripping program such as dvdshrink or dvd decrypter - The older disc's were locked using a layered menu structure but the new ones are being done with a unique to disc algorythm - I doubt that you will be able to crack or even demux one of the latest releases but please keep trying. I know alot about this subject because I am one of the developers and authors of the technology.

What technology are you talking about? Unique disc algorithm ? - were talking about a DVD here right? This is just a simple passcode. Granted you'll need to know how to track GPRMs and see how the code was written but this should be fairly easy to do with any tool that allows to track pre and post commands.

You should be talking to the Hollywood Studios, they'll pay big bucks if you can stop a hack.

[telfraser]

The dvd that he is talking about was one of the older discs and just used a layered menu - in response to clients and for ease of authoring - the process was changed - it has been tested with regards to ifo editing software and other 1 click conversion software such as dvdshrink. The protection is not suitable nor adaptable to large volume releases such as main stream movies not because it wouldn't work but because of other non programing contraints. The market the pin and play dvd's are aimed at, and the business model used, means that the new protection and pin can be used. Once blue ray is in common use, this technology would be able to be used. Nothing is unbreakable but the nature of this protection is that without a serial code you wont be able to view the material and the volume of each DVD run is small - so no programmer will invest the time especially as each release a new serial algoryhm is used (thats the real reason Apple are relatively virus and malware free - to small relative to the entire computer market and no return for the person writing the virus or malware). The disc is aimed at a niche market - its been tested in other markets but its commercial constraints not programing that stop the process being used generally - The new discs are free give aways on Adult magazines so you can acquire one and try to hack it

[videopoo]

I'm sorry...you don't really explain how this copy protection is applied to the disc. Is the OP talking about a PIN involving menu design and authoring or is it something else? I have several clients in need of something like this so could you post a link or perhaps a way to contact you?

Could you give out any names of disc so I could test it? I live in California so I'm not too sure where to go? or maybe PM me.

[telfraser]

The actual locking system can be used in other situations but the commercial reality is that the adult market can utilize the product and pay for the authoring. The company that does the locking also does the authoring - this makes it even more secure. In the Uk and Europe the discs are given away free with adult magazines and a percentage of people utilize the disc (called the pick up rate), the pickup rate is important - with adult material you are guaranteed a certain pickup rate. I have looked at other niche markets but none seem to be able to support the volume and pickup rate needed-

[videopoo]

I guess I'm trying to figure out what special process you provide to make these disc "un-hackable"? Anyone can author in a passcode to a disc and determine the code from looking at the disc's structure in any DVD editing tool.

What I'm trying to find out is this process you've developed in the authoring stage or afterwards? Yes or No?

You say that DVD editing tools like PGC Edit or DVDAfter Edit won't allow you to open your discs and see the code correct? You said anything is hackable but thats not what the OP was asking...If its a DVD and contains a passcode, anyone can get the code if they know what to do.

I just want to clear up any confusion here. I'd hate to think your simply authoring in a passcode to a DVD and selling it off as some kind of new proprietary technology.

[telfraser]

We no longer use Scenarist - here in Europe Companies are moving away to specailist purpose authoring software - Keep hearing good things about "Tosh" but havn't had access to it yet.

[videopoo]

Had a look at your website - you don't seem to have a client base hat we would deem suitable for a lock and pay situation finance wise but good luck with the interactive DVD'S (Its an area I am personally much more interested in - ours allow downloads,other media, web links, printing, SMS and Ip phone - we designed them for Large Scale property developers - Dubai, Spain Turkey etc)

Since I don't list most of my past., present or future clients on my site...I'm not sure how you'd come to that conclusion? But then again..I don't do much porn. Good Luck

Hi all,

We have a product called DVDPay that provides the functionality you have been discussing, but rather than a static single PIN that dany_boy described we embed an algorithm onto the DVD which calculates a different PIN per user - just as Telfraser has seen in the market. We have no association with Telfraser but after seeing that he had apparently developed something which sounds remarkably like our Patent Pending product I managed to track him down and speak to him on the phone. It turned out that he was talking about our locking technology with the algorithm and didn't mean to mislead by saying that he had developed it.

To answer the questions from this thread:

What technology are you talking about? Unique disc algorithm ? - were talking about a DVD here right? This is just a simple passcode.

Yes the DVDs are just "normal" DVDs, but we embed an algorithm onto the disc that validates that the PIN entered by the viewer was the correct PIN issued to them.

Is the OP talking about a PIN involving menu design and authoring or is it something else? I have several clients in need of something like this so could you post a link or perhaps a way to contact you?

The PIN involves both menu design and authoring. The quickest way to explain it is that the viewer clicks on a link on the main menu and is advised that there is a locked section. To watch the locked section they must obtain a PIN to unlock it and they can purchase one by calling a premium rate line, texting in to our mobile shortcode or calling a freephone number and paying by credit card (or if the client wants to give a free PIN this can be given via a freephone number / shortcode).
The viewer simply follows the on screen instructions to get their PIN, then they select "next" and enter their details. The DVD checks if their details are correct and if so automatically plays the film (or if the client requests shows them a chapter menu for the locked film). If the PIN is incorrect the viewer is advised that it didn't check out, and is given the option to re-enter their details (or to go to the main menu).

Does it work in the States?

It sure does, regardless of what "Telfraser" seems to think. It also works in the UK, Canada and Scandinavian countries. We're developing more countries at the moment.

What I'm trying to find out is this process you've developed in the authoring stage or afterwards? Yes or No?

We author the DVD from files given from the client and provide a final master for replication. i.e. our clients would send us the films and titles for the disc, we would add these together with our locking technology and send them back a master disc.

I have several clients in need of something like this so could you post a link or perhaps a way to contact you?

Please feel free to PM me, email me via my videohelp profile or checkout our website for telephone details - www.dvdpay.net - If you're not UK based then please PM me for a direct line.

Well, considering that he said in this thread:

Yeah, I think his post was misleading.

By the way David, your post is arguably a commercial solicitation and may be in violation of forum rules should the moderators view it as such.

hello
My name is Tel Fraser
there are four DVD AUTHORING Companies that have individual serial codes for DVD's. We were phoned by a company who stated they had a patent pending serial code situation - good for them - according to legal advice taken by myself and other groups- it is unlikely to be patentable. I told the company representative that we weren't interested in the "Adult Market" and left it that. We don't solicite work we are project based so please don't think this reply is anything other than setting the record straight.

[DavidMorris]

removed at Jman98's request

[jman98]

telfraser and DavidMorris - Can you please take this stuff off the forum and communicate directly with each other? Talking about who invented what, who has patents and such is pretty far removed from the original post where some guy just wanted to hack a porno DVD with a code on it. I really don't care at all about your business.

[DavidMorris]

Good point, I've removed that last post.

dany_boy - did you ever work out how to get round the PIN entry bit?

Thanks,

David

[Bandaren]

Ok I got myself one of theese pin protected discs and this is how I solved it. (I won't post the code)

First it's important to understand that atleast on my disc this pin verification is not actual numbers compared to a database.

What happens is that we are just navigating through 4 sets of menues with 10 buttons each (the numeric pad). The pin is 4 "numbers" but you will only see 3 "*" being shown, when you press the fourth you either get "wrong pin" or the movie starts.
Buttons leads to the next set of buttons that replaces the old matrix transparantly and with some nifty voodo in the ifo files with comparing numbers in assigned variables and some dummy graphics to boot it all looks like a pin code verification process.

This is probably a very shallow description on how it really works but if someone wants to go into it further please do.

So what I did was to use PGC Edit with its feature to preview the dvds menue while showing information about the buttons. With it I stepped through the numeric menue pad to see which buttons lead to another unique set.
9 buttons would lead to a "wrong path" menue, all having the same name while 1 button would lead ahead to another set with a unique name "correct path".

On my disc there is a Master pin code that unlocked two movies and induvidual chapter codes so there is a fair bit of stepping around to do if you want them all. Although the Master Pin code is all that you really need.

I hope this helps.

[videopoo]

Thanks! Thats pretty much the conclusion I came too earlier in this thread. The guy was trying to claim that he was using some patentable new technology when, actually, he was just using the registers available in the DVD VM code.

[SweetthD3ViL]

Will love to know how you did to find out those pin, would you mind doing a quick howto?

Many thanks,

[El Heggunte]

JMHO — it'd be much easier (OR "more fun" ) to rip the "protected DVD" to the HDD,
demux only the "relevant" parts,
re-author with any decent freeware,
burn it on a DVD-R.

[SweetthD3ViL]

I am more interesting in trying to understand more about pgcedit than the content

[crixpit]

title screen it has a 3 digit pin number men...
I have never come across this before?

I have. It's a template in a MediaChance DVD lab pro

here's how to set it up (yes, I realize that is not the intent of OP question)

Hello, I've installed PGCEdit and I've loaded the DVD, I found the specific movie files and previewed them, but I don't know how to look for the 4 digit pincode required to view the movies on disk. I tried to use a decriptor but it ran into errors (with the free movies on disk). I was wondering if there is a guide to removing, bypassing, finding the pincode to such a DVD.

There are 6 protected movies each with a pincode. There is also 1 master pincode to unlock them all.

[r0lZ]

If you can navigate to the master password input (with a real DVD player), then I suggest using the Trace mode of PgcEdit to find the code. You don't need technical knowledge to use the procedure described below.

1. Load the DVD and enter trace mode (Trace menu -> Trace Mode). Click the [ Run ->>>] button in the virtual player (in the bottom left part of the main PgcEdit window). PgcEdit simulates now what a real player should do. If you see a video in the preview window, you can close it. When PgcEdit shows you a menu with buttons, select the right button and click [ Select ] to continue.

2. When the first screen of the master password is shown, do not close it, and do this: Select the menu State -> Snapshot State -> User Bank 1 (in the menu of the virtual player in the bottom part of the PgcEdit window). Doing so will allow you to return easily to that menu. We will need that later...

3. You are now in the menu corresponding to the "Start" thumbnail in post #27 above. Select the button "1" and continue. You will probably have selected the wrong button, so when a new password menu is shown, you are probably at thumbnail "BAD1". Note the current PGC label at the top of the menu viewer window. (The PGC, PG and Cell numbers are especially important.)

4. Now, hit [Select & Break] in the menu viewer to stop the trace, then select the menu State -> Restore State -> User Bank 1: ... and press [ Run ->>>]. This has the effect of undoing what you did since you have saved the user bank 1, so you are again in the "Start" password screen. Now, click the "2" button. Again, there are chance that it's not the right first digit. If it's the case, the label in the menu viewer should be the label you wrote at the previous step.

5. Repeat the previous step, clicking "3", "4" etc... until you see another label in the menu viewer. Now, you are in "GOOD1", and you know the first digit of the code. (Of course, if, per chance, the right button was button 1 or 2, return to that button.)

6. Now, you will need to return to the "GOOD1" screen easily, so snapshot it in User Bank 2. Repeat the procedure described above, from step 3 (and replace "Start" with "GOOD1", "BAD1" with "BAD2" and user bank 1 with User Bank 2). After a few tries, you should know the second digit, and be in "GOOD2". Snapshot it in bank 3, and repeat again the procedure to discover the last digit.

7. Confirm by restarting the trace mode (click the button with the Eject icon in the virtual player then [ Run ->>> ]), and enter the 3 digits when prompted. PgcEdit should continue to the movie.

That's all!


A few notes:

Of course, the same procedure should work also for the individual passwords.

It might be possible to discover the right digit more easily than with the method described above. When you are in "Start", "GOOD1" or "GOOD2", just select the menu button "1" (but do not click [ Select ]). Have a look at the command in the big button just below the menu image. Now, click "2" and look at the command. Repeat for all buttons. If one (and only one) menu button has a different command than the other buttons, then it's almost certainly the right digit!

It is also possible to implement the password logic using only a single menu screen, and many commands and/or superposed buttons. If it's the case, you will not see changes in the PGC labels in the menu viewer, and the procedure above will not work. But since implementing the password using pure logic is difficult and doesn't permit to show the stars in the LCD display of the menu, I suppose that a simpler method is used. Anyway, post here if my procedure doesn't work.

It is possible to remove completely the password screen to go directly to the movie, but the procedure depends of the structure of the menu and its logic. If you are interested, let me know...

[Descrasnezul]

I am in the saved state of entering the first digit. Ive taken note of the label for each of the numbers
VMGM ,LU 1 (EN) ,14 (0:00) 12B

But each digit 0-9 have that label by the time they get to the screen to select digit 2. I don't see any changes.
