Copy Protection on a DVD-R disc - how to bypass?

[nerys]

I have a DVD-R Film. Yes its a purple dvd-r

For some reason I can not copy this disc. its shows as invalid. I load it up in dvdfab shrink and decrypter and it either shows as odd or as some crazy small number (100mb or 15mb)

I load it up into explorer and WOW talk about structure obfuscation

it shows 421 files totaling 69.5GB clearly impossible.

SO this is some form of "structure protection" on a DVD-R

how do I go about defeating this? I can't even do a disc to disc copy (says invalid in nero)

I assume you will need some info about the disc (its not your normal hollywood disc its an adult dvd)

Just tell me what software and how to get it and I will provide it.

Thanks

[Moontrash]

might try dvd43...i guess it all depends on how new the dvd actually is...dvd43 may sneak in there and decrypt it or, it just may be a newer protection that they haven't updated yet

[DB83]

But does the disk play in a stand-alone AND a software player ?

[lordsmurf]

General DVD-R cannot be copy protected. It's just a bad disc, if anything.
Not being copy-able is not the same as being protected.

[nerys]

It appears to be structure protection. IE a bunch of "fake" files that come to 69.5gb it plays in a DVD player just fine. I don't have a normal DVD soft player so I can not try that yet. Windows explorer shows the size properly but once you go into the video ts folder

[nerys]

The disc itself is odd as well. I am thinking its a multisession disc and all those "little" sessions contain the faked data obfuscating the real data (the large section)

[jman98]

Try to read it with DVDFabHD Decrypter. I suppose anything is possible, but I would say it's unlikely that the porn industry has figured out a superior form of copy protection to Hollywood.

Thanks for the additional info. I believe that your conclusion that the disc has special copy protection on it is correct. However, Hollywood has tried somewhat similar tactics in the past and DVDFabHD Decrypter has been able to defeat those, so give it a chance.

[DB83]

Have you tried imgburn to do a sector by sector image read/create and then burn ?

Or

You can send me the disk. I may not be able to copy it but I might enjoy the content.

[nerys]

I am using DVDFAB 6.2.0.5

I will download the latest version and see what happens.

its not "copy protection" in the conventional sense. its Structure Protection. IE they obfuscate the content with a bunch of "fake" content. normal CSS Encryption won't work on DVD-R as lordsmurf noted.

but that does not stop them using "other" means of protection.

[funnel71]

Might I ask - how was it made? I've encountered discs that if recorded on a stand-alone type DVD burner, and the disc was not "closed" via that player, it won't seem to play in anything else.

[nerys]

I have no idea how it was made. I also am VERY curious how they did it. it plays just fine. It just won't "rip"

[Moontrash]

if its not copy protection, then try this...

use ripit4me....it can usually detect bad sectors or fake/bad vts'

or

try using vobblanker...it also can see those bad spots

[nerys]

I will try both of them. I installed DVFAB 8.0.1.5 and so far its working but not on all of them. I will give ripit4me a try.

Not sure what "... not on all of them" means as if it works correctly it will get rid of the garbage. You shouldn't see all the bad structures from the DVD if the rip works correctly.

VOBBlanker is not a ripper. Keep that in mind.

RipIt4Me hasn't been updated in years because the person who wrote it was given an offer he could not refuse that in exchange for not taking him to court he had to abandon the program. Consequently I would not find it likely that RipIt4Me will work if DVDFabHD Decrypter doesn't, but I suppose there's no harm in trying.

[nerys]

Sorry I have several disks. the newer dvdfab worked on the first one but has not worked on any others "so far"

These others are strange. they appear NORMAL besides the addition of two new files.

a .layout file and a .LAY file.

Very strange to have so many odd disks all at once. Its so far letting simply COPY the video_ts directory. I am going to try that and see if nero will burn it.

Nero has not balked yet so we shall see. I am curious why the rippers are unable to "see" the disc even though so far it seems to have ZERO protection at all.

Huh it works fine. Once I manually copied all the files in the vieo ts folder and burned them it worked FINE in dvd fab. Very very strange.

it appears only that first disc has the structure protection (and the new version of dvd fab ate that up nicely)

the rest of these so far are either flat out "frakked" in some way or have some very odd but puny protection.

I can copy them but not rip them. once I copy them I can rip the copy. So I am starting to think many of these are "bad closures" (its strange set top players usually puke on bad closures) so dvd fab can not see it but windows see's it just fine so it copies it just fine and since my copy is "closed" properly it reads fine in dvd fab.

Very very unusual.

the one disc with structure protection is this much stranger.

If I do a full rip it works but the resulting burned disc will not play (disc error) and it has a TON of vob files.

if I do a MOVIE ONLY rip it rips fine just 3 vobs but the burned disc still won't play

Freaky strange stuff

I tried reauthoring the vobs but dvd author complaines that they are illegal format files.

Here is what kmplayer gives me

Not sure what is wrong with this file. Could it be the PCM audio?

So far the rest work fine if I manually copy the video ts folder and reburn it. Very strange.

I have seen a few of these diiscs - mind you I'm well over the hill to be interested in adult content I helped a friend make a back up copy a few months. What we finally did was drag all the VOB files into Womble and then remove what was not needed and exported a normal MPEG2 file and selected MPA audio. Womble basically did a stream copy of the video and reencoded the audio. He then made his own DVD from that as a viewing copy and put the original in a safe place for storage... You could also take a look at the IFO files to find out whats happening..

[nerys]

yeah I guess thats not too hard. Its just odd that the files CAME FROM a dvd and played back FINE as a dvd.

Very odd I got a few of them done gave up for tonight will give them another crack tomorrow.

Our use is legit. we have a viewing system. Problem is the system is now fully digital. I rip the dvd to a flash card and pop that into the player for that weeks film cycle.

I could always play/record but man thats 1 hour each real time recording - what a drag

[nerys]

got another one today. claims to be 379gb for a 3.95gb disc 597 files about 100 "sets" of vobs.

going to try those 2 programs and see if they can "find" the real ones. ripit4me seems to be working on these.

[Slingal]

I have also seen this protection. It is used on commercial DVD-R disks (as sold on Amazon). These disks are used for movies that do not generate enough sales for a pressing. If you look close on the back of the DVD case you will see a notice that it is a DVD-R and may not be compatiable with all DVD players. I tried using AnyDVD to bust the protection but it still showed 68Gig of data.

[nerys]

rip it for me works to get the valid vobs but I am trying to find a way to avoid authoring my own disc.

is there a simple program to take vobs and add the support files to make it play (no menu's) as a valid dvd ?

[manono]

IFOEdit, at the bottom center, Create IFOs.

[dylz]

I had a couple of dvd's that I tried to edit without knowledge on pgcedit well after the edits i didn't have a backup and I tried to open in dvdfab, it saiod the size was 10-20mb when it's 6gb well I opened back in pgcedit and there was a couple ïllegal instructions (highlighted in red) so I deleted and like magic dvdfab could open them with all titles showing up, the dvd's did work in a dvd player and copying/editing programs couldn't until I fixed the commands.

[nerys]

Just wanted to update you guys. SO FAR ripit4me is working. its a SERIOUS pain in the butt. I have to manually and miticulously walk the process step by step and its aggravating but so far it seems to be working.

I hope someone figures out a way to do this WITHOUT all this crap IE click and go when I try one click mode in ripit4me it wants to rip the 597gigs of fictional content of course Can't do that I don't have a spare TB lying around.

so I had to do the wizard mode manually and it is VERY manual except for a few steps. Constant baby sitting to click ok to this next to that yes I am sure to this etc.. etc..

good news is I end up in shrink and don't have to mess with making it a valid dvd.

bad news is this only works for movie only. it can rip the menu's but it rips 99 menu's and it can't seem to tell which one is the real one. Grrrr

but the system does not need menu's so thats ok.

apparently "clone mode" works in dvdfab (I have not tried it others have claim it works) but you still end up with the obfuscated dvd that way so no good for the video system.

Hopefully as more people encounter these discs (concerts use it and apparently warner back catalog service uses it too) someone will find a more elegant solution

[mazinz]

In all seriousness do you have another type (as in brand) of PC dvd drive you can try the disc in or even on a friends system? Quite a number of people have had issues in trying to back up similar burn on demand disc like yours. In many cases it also had to due with the type of dvd drive being used and it's ability to read the disc (one thing mentioned was that newer drives were made to be a bit more sensitive to the protection on a dvd-r BOD disc while older drives were not).
I have two liteons (one rom, the other a burner) and a pioneer and never had any sort of trouble backing up any type of burn on demand media, yet quite a number of others could barely get their pc drives to actually acknowledge the disc was in the drive, much less being able copy it

[El Heggunte]

Just out of curiosity,
has anyone already tried to read those weird DVD-Rs with IsoBuster?

[nerys]

Oh yes. I have 8 stations at work with 2 DVD drives in each one and they all tend to be different (for just the reason you suspect) sometimes one type of drive throws a fit about a disk but another takes it just fine.

I also have 2 laptops one with dual drives the other with dual external drives and one internet.

I also have 2 systems at home. all read the disk fine.as 597gb hehe

I will try to remember to try isobuster tomorrow.
