Cannot backup R2 Seinfeld Season 4 Disc 2

[Malphas]

Can anyone help me out with this? Here's the steps I took:

1) Tryed to rip as per usual with DVD Decrypter, got some error, wiped the disc's surface and tried a few more times, no luck, assumed it must be a form of ARccOS that Decrypter can't handle.

2) Downloaded the trial version of AnyDVD and used it in conjuction with DVD Decrypter to rip the DVD (file mode), seems to work fine.

3) Opened the files with Rebuilder, used the HC encoder set at best quality, pretty much default settings.

At 13.4% through the Rebuild stage I get the following error:


ERROR 0006: DVD-RB has found framecount differences between the PREPARE and REBUILD phases. Aborting.

I understand that due to the nature of the disc it may well not be Rebuilder's fault but thought this was probably the best place to ask anyway. Whilst searching for information regarding this I found various threads elsewhere where people claimed to have success using DVD Shrink. I haven't verified this myself though. I also tried the whole thing again using DVDFab Decrypter, it produced the exact same error.


Software used:

DVD Decrypter 3.5.4.0

AnyDVD 5.4.4.1 (Trial Version)

DVD Rebuilder Pro v1.00 RC6

DVDFab Decrypter 2.9.5.0

If using the DVD Decrypter/AnyDVD combination did you also change the I/O setting in DVD Decrypter so that AnyDVD is the thing that actually decodes any protection while DVD Decrypter does the job of ripping

This is what the settings are as suggested by the guy that writes AnyDVD

In DVD Decrypter settings :

I/O : Change the interface setting to show "Elby CDIO - Elaborate Bytes"

General : Disable the "Check For Structure Protection" by making sure the option box is unticked/empty


This turns off DVD Decrypter decoding any protection and passes control over to AnyDVD for protection removal


I use this combination myself and have had no problems at all with any protected DVD

Also I forgot you MUST reset the computer after installing AnyDVD otherwise it will NOT detect any drives correctly. Its a pain to reset your system just for a software installation, but this is very important in this case

That's exactly what I did. It's not really the ripping part that gives me trouble; like I said it appears as though it rips fine, it's only when rebuilding that I ran into problems.

[Mr. Monte]

Iv'e read where some of the DVD structures are not correct from the git-go. You might try running the ripped folder through VOBBlanker (without blanking anything) and see if VOBBlanker finds some errors and corrects them.

Or if it works with DVDShrink..run it through Shrink with NO compression onto tyour hard drive in a different folder and then use DVDRB

[Malphas]

Didn't work I'm afraid. I just had to use DVD Shrink in the end.

I have made a backup of all R2 Seinfeld discs. I just don't remeber if they had a protection scheme.

But I', sure that I had DVDDECRYPTOR alone and was doing the job greatly.....

So maybe the problem is quite simple:

You have a defective DVD with read-errors just as a result of bad manufacturing.

Then DVD-DECRYPTER will report these errors as REAL read-errors and not errors in the protected area (for the R2 Seinfeld discs, not taking into account the lastest protection schemes).

Using ANYDVD can help. I even noticed, with the latest version, the IO setting of DVDdecryptor is not important, bu correct me if I'm wrong here.

The problem is that ALL RIPPING SOFTWARE SHOULD MAKE DIFFFERENCE BETWEEN READ-ERRORS caused by a protection scheme or REAL READ-ERRORS THAT ARE REAL considering REAL DATA.

DVDFAB for example replaces every read-error with a dummy sector.

Even the dummy sectors introduced bij tools like ANYDVD and DVDDECRYPTOR can comletely mess up DVD-RB. This is not a fault of DVD-RB (although maybe something can be done to handle these dummy sectors) but of incorrect structure and sector content.

The only and surest way is to rip the DVD and make sure there are no READ-ERRORS on the DVD by accident or malfunction or just a bad DVD. I've seen this often in my backup practise that DVD's contains read-errors, while the stand-alone player showed nothing special (or just a 0.1 second skip or green bar). That's bescause a standalone player read as much data as possible regardless 'official read-errors' or not.

Then the second point is to remove the dummy sectors....

I use DVDREMAKE-PRO for that and simply remove all cells that are part of the copy-protection. Even I check the first playble cell, because it often conains one or two VOBU's that are not ok. I remove these too.

After that I have a fully compliant DVD. And DVD-RB processes it without problems.

By the way SEINFELD R2 discs have no copy protection I remember more clearly now, so the changes are big they were just 'normal' read-errors.

Commercials discs to sometimes contain read-errors, and often that's not a problem when playing back with a stand-alone player, that ignores them and tries to get the info it needs out of them.
If there are a lot of read-errors in a row, then even on a stand-alone player they are just sometimes not visible or only sometimes by a flashing green bar for less then 0.1 second. But computers are computers and they will complain about every little sector read-error. If the sector was 'repaired' by the ripping tool as stand-alone DVD-players do, there would be (almost) nothing wrong, but ripping software inserts 'dummy sectors' without even trying to find out what kind of sector it should be..... A stand-alone player makes assumptions on the fly when this happens. The ripping tools nowdays are not so intelligent they replace the sector with a sector to expect, and can cause big problems when using strict software like DVD-RB-PRO.

If you use DVDdecryptor you can see where the exact read-errors start.

If you try a second time and they start on another sector-number (LBA in DVDDECRYPTOR) you can be sure it are not read-errors regarding to copy protection. Even try another reader if you have one.

Copy protection read-errors are hard-coded on the disc an they will always be there at the same place, everytime on every drive.......

I assume by no copy-protection you actually mean no-ARccOS, there's definitely CSS obviously. Perhaps it varies from disc to disc but some guy from SlySoft said:

Seinfeld Season 4 RC2 has a different Arccos version, which is only partly removed.
An updated AnyDVD version will be available within the next 24 hours.

And if you Google on the topic (http://www.google.co.uk/search?hl=en&q=seinfeld+r2+copy-protection&btnG=Google+Search&meta=) you get a lot of results with people having trouble with these particular discs and more information on the possible protection used, which would suggest that you're either mistaken in this instance or perhaps the versions differ.

Thanks for the advice though, I may try out some of those suggestions. As I mentioned in my original post, I already tryed ripping multiple times so I doubt it was just a read error; unless, like you said, I have a faulty disc, but then I don't see why using DVDFabDecrypter or DVD Decrypter + AnyDVD would have cured this.
