Prot DVD test results

[mats.hogberg]

As we all know, there are claims that you and me can create a copy protected DVD. Some say this is not possible, some say it is. To put an end to guesswork and idle opinions, a test image has been made available by ilovevcd.

PM ilovevcd for a link to the test image.

Post your objective findings in this thread - Test playback, test rippers.

If you've not tried the test image - don't post in this thread.
When you post - just post what works and what doesn't work.
Any subjective comments will be removed.

Rippers:
Acidrip - No
DVD::RIP - No
DVDFab HD Decrypter v 4.0.1.2 - No (using Wine)

Software Players:
Totem - No
MPlayer - No
gXine - No
VLC - Yes

Hardware Players:
PS2 Slim: - No (Bad disk)
Samsung DVD HR757 - No (System error has occured. Try again after power off)
Matsui DVD227 - No (Just displays the disk as a Data disk(directory))
Centrum Gemini 340 (NetOnNet Vestel clone) - No (Says "Play" but never leaves the standby screen)

I'll add a few rippers and players more as I try them out.

Rippers:

DVD Decrypter in ISO read mode = Yes

Soft Player:

PowerDVD 7 in File Mode = Yes

Hardware Player:

Funai DRVR-B778S = No

Update:

Ripper:

Ultra-Iso reports different files in the iso created from DVD-Decrypter. When extracted these are 0 length and not the reported size = No

[Dv8ted2]

IMGburn - defeated the protection in read mode.

Playback in wmp. - successful

This shows up as a cdrom.

Will report more later

[Dv8ted2]

I was able to copy the files using copy and paste in windows explorer.

Could not play with media player classic.

Ifoedit failed

Yep, it also show's up as that in every program i checked.

And DvdInfoPro reports it as NOT A DVD VIDEO





I feel like i'm on an episode of Mythbusters

[rkr1958]

I've confused here ... downloaded ntsc-prot.zip, extracted and ran ntsc-prot.exe . Then I got ntsc-prot.iso. For grins, I mounted the iso using VirtualCloneDrive (from slysoft) and tried to play the mounted video first using WinDVD 4 and then VideoLAN. Some video flashed up for a second or two then stopped. Before I go to the trouble of burning the iso to a DVD and trying that should I be able to play the mounted iso and see a meaningful video? What am I missing here?

[rkr1958]

O.K. Please bear with me then ... is the objective of the "copy protected" DVD to be playable only on settop players and not playable or copyable via computer?

[DB83]

The only thing that puzzles me is that this is what Ultra-iso reports from the iso created from DVD-decrypter



whereas the original iso only shows two files with any data :-

video_ts.vob
vts_01_0.vob

all the rest show up as zero size.

So are we missing something. An iso has been created from a disk which preportedly you cannot copy. The iso seems to be generally unplayable although it can be copied.

Is the above image more representative of the original disk ?

[disturbed1]

It's not a valid DVD image. I didn't even bother to write it.

The VIDEO_TS.IFO and VIDEO_TS.BUP files are just empty txt files. A real VIDEO_TS.IFO and VIDEO_TS.BUP file is an octal stream. No reason to continue further.

Waste of time.

O.K. Please bear with me then ... is the objective of the "copy protected" DVD to be playable only on settop players and not playable or copyable via computer?

I designed it to be run on stand-alone players only
NO Computers NO

To entertain the idea a little more

I redownloaded the file, and actually burnt the disc. But, before burning I created an MD5 checksum of the iso image

Playback results -
Panasonic S35 - No Disc
Philips DVP642 - Endless play cycle. Only displays "PLAY" on the unit, no button does anything. Machine did not lock up.
Toshiba HD-A2 - No Disc

I used a Fuji Film MIJ (TY02) DVD+R book typed to DVD-ROM, burnt at 8x with Nero Linux 3.0.

Then I popped the disc back in my PC's DVD drive (Lite On in my details) and issued the following command

dd if=/dev/scd0 of=/home/disturbed1/foobar.iso

Then created both an MD5 checksum of that iso, and of the disc in the drive itself.

MD5SUMS
ORIGINAL - 527c46779afd97a6ac0b2b2671d522ee ntsc-prot.iso
COPIED ISO - 527c46779afd97a6ac0b2b2671d522ee foobar.iso
DISC - 527c46779afd97a6ac0b2b2671d522ee /dev/scd0


Results, the image did not play in my 3 set top DVD players, but was able to be copied bit for bit Fail at producing a playable DVD-VIDEO, Fail at copy protection.

BTW, the iso image was playable with VLC. It was about 18 seconds, screenshots included. This was from the copied iso image.

[ilovevcd]

Thanks for all downloads and showed interest.

However, since there was so many player that did not played the disc i was investigateing in the problem
and fixed some issues that some of my player complained over.

So for those who would like to give the sample a second chance it on the server for download.
If you don't have an account send me a PM and i'll fix you an account

And thanks for your help

Best regards ILoveVCD

[DB83]

Well, the issues are still the same for me.

The iso shows files with data (probably reading the TOC) but have 0 bytes when extracted.

And if you cannot copy it how can you create a valid ISO in the first place ?

[ilovevcd]

Did you tried to play it on stand-alone player?

Well, there is 2 ways on burning dvd
1. You burn on the fly without an image file
2. Burn the dvd from a image

I did the second one. But if the image you burn, never been o a disc before who knows what it contains.
But trying to ripp from an burned disc can give different results depending on the program used.

Also:

Have you tried DVDHdfab or some other program to rip it?

[DB83]

But surely an ISO is an EXACT image of the disk that will be created.

I burnt the original ISO straight to disk. I reported the issue I had - files having different properties.

So this time I simply rip the ISO with the intent to burn the files.

But AGAIN, the ripped files are different to what the ISO read is telling me.

[ilovevcd]

But surely an ISO is an EXACT image of the disk that will be created..

Well this is suposed to be a dam hard to dvd to rip (or copyprotected)

If all was well with the image it would be not match for any one to copy it, right?

But you can still not play it on a standalone?

[DB83]

Ok. For the sake of 20p (yeah Verbatim's are expensive over here ) I burnt the ISO using Imgburn this time.

In my Funai Standalone I get a menu and 18 seconds of movie with sound - some full screen and some in a small window. So that = Yes (if that is all I am supposed to see)

PowerDVD 7 is still = No

Watch this space for RIP results.

[ilovevcd]

OK, this is all but the reason for the image to be 4GB is that some player need at leat 3.8 - 4GB to be burned otherwise it does not play properly or does not play at all

Now try copy the disk with dvddecrypter in iso-mode and you can also try dvdfab to rip the dic.

Then if you have not done so, check the content of vts_01_1.vob and also the vts_01_0.IFO files to see whats in them
You can also check those files directly from the dvd if possible.

Besacue some people thinks that just because they are able to copy the files to HD, they should contain correct data.

Did my previous disc played also or is just this one that plays?

[Noahtuck]

Besacue some people thinks that just be able to copy them to HD is done, they should contain correct data.

But when the original ISO does not even play in most standalones.... ripping in irrelevant..

[ilovevcd]

Yes, but i fixed that issue, and DB83 said that it play in his funai but the first one did not

So if you like, login and download the rc_1 version.

[DB83]

In for a penny.

Ripped under ISO read mode with DVD decrypter ignoring the errors that were displayed.

Burnt that ISO using Imgburn (cos that is what I used to burn the original - 2nd - ISO)

That 2nd disk ALSO plays in my Funai. = RIP/Copy = Yes !!!!!

Oops. That is not what is supposed to happen

[ilovevcd]

Well it was not what i excpected, but thanks anyway. Now i have to checkit my self.

Yea, got a anoter one in this forum that was able to copy it under linux.

But stated way back, when i started to create a protection system i said:

1. Stop computers from filecopy (like copy cdrom:\*.* c:\data\)
2. Jerk up the IFO system
3. Stop Disc-copy

And so far i think 1 and 2 is quite ok covered. Or what do you think?

[Supreme2k]

DB83, help me understand you correctly:

1. You downloaded the latest build of the ISO.
2. You burnt the ISO using imgburn
3. You extracted an ISO from the burn in step 2 using DVDDecrypter (Not DVDfab, right?).
4. You burned the new ISO with imgburn, and it played

Does it play in your PC?

I was going to test this thing out myself, but from the looks of things, it would be a waste of time and a blank.

OK, this is all but the reason for the image to be 4GB is that some player need at least 3.8 - 4GB to be burned otherwise it does not play properly or does not play at all

I've done quite a few under 2GB discs, and they play fine on every player I've run them through, even a friend's old Samsung that was one of the first to play burned discs.

And why the revisions already? From the previous thread, you pretty much guaranteed a fail-safe system. This was supposed to be a challenge, not a bug-hunt.

Many players have issues seeing a disc under 2,000 sectors (~4GB).

[ilovevcd]

Well, as everybody here says, copy protection violates the DVD-spec.

There was not any problem in my protection when it came to stop the computer from file access, but i improved the player compability. Since too many had problem playing the disc i had to do something.

[Dv8ted2]

You forgot I was able to copy through windows explorer. That was a big time goof on your part. You must have eaten crow on that one.

I am also able to rip with imgburn - strike 2

Hardware players

Norcent D315 - showed file menu then played - did not play directly - I would consider this a fail
Symphonic DVD/VCR - played only the first image - fail
Cyberhome DVD - played only the first image - fail

This is still showing up as a cdrom.

I would say that you failed at copy protection.

[DB83]

Just to clarify.

The original burnt ISO (using imgburn) would not play in the PC (using PowerDVD) but played on my Funai

The ripped/burnt ISO using dvd decrypter/imgburn (I would expect,but do not intend to try, imgburn to perform both functions fine) would play on my Funai but not in the PC.

He still failed, because you were able to copy it. I was able to copy as well. I burned with imgburn and ripped with imgburn.

[lordsmurf]

I burned and tested this stupid disc. I got the image from another forum member. It fails to work on 100% of the software and hardware DVD players tested. It copies in Windows Explorer, of all things. As a "copy protection" it fails completely. And to top it off, it's not even close to being a DVD-Video anymore, it's just butchered data on a disc.

Quit deleting posts that you don't like.

Why are we coddling stupid ideas?
Can I start a thread about how to scratch a disc, as a form of copy protection?
