DVD Ripping Question regarding possible new copy protection

[hawthorn]

Most the time I have no probs, but just recently I had tried backing up Brother in Arms and also Hitch, and both of them came up with an error message saying "data error (cyclic redundancy check)". Both the DVD's on the data side of the disc where it has lots of numbers etc, say Sony DADC along with many other numbers and letters.

Do DVD's having Sony DADC written on the bottom of them near the centre part of the disc, have a better type of Copy protection that programs that are usually ever reliable like DVD Shrink 3.0 Beta edition are not able to bypass? Or can someone tell me how to bypass this problem that has only ever happened with these two DVD's (they did not have any finger prints or scratches on the disc either). Trying to rip those two dvd's seemed to send my DVDRW drive I put it in to rip into a state where it could not read any DVD or even eject the DVD until I switched off my computer.

If someone has actually backed up Hitch or Brother in Arms, can you let me know what program(s) you used to do so?

Since those DVD's I have back up a few more and they all worked fine so it has not stuffed my DVD drives, but it does seem that something is different with those two dvd's to what is the case with every other dvd I have tried to back up.

Thanks in advance for any help you can give me.

what are you using to rip the dvd? others have had a little trouble with ripping hitch but it is possible, search on the forum it's in here... and try dvd fab decrypter if you have not.

Try alternative rippers like DVD Decrypter, DVDFab Decrypter and ISOBuster. Maybe one of them will have success ripping the disc. Also, try AnyDVD.

'cyclic redundancy error' sounds more like a faulty media issue than any new copy protection.

'Hitch' needs to be ripped with a program like DVDFab Decrypter. Just backed up my copy and Fab works with no problems. Then I used DVDShrink to lose the extras and Nero to burn.

EDIT: Here's a link to a list of movies DVDShrink has problems with:http://forum.digital-digest.com/showthread.php?s=&threadid=48842

Hi
I just downloaded, dvdfab and dvdshrink. I intend to, as suggested, backup a copy protedted dvd with dvdfab and then use dvdshrink to remove the extras so will fit into a dvd+r then burn using nero. Is there instructions on how to use these 2 programs to do the above. This is my first attempt.
Many Thanks
Pat

DVDFab really needs no instructions. It just rips the entire DVD to your harddrive. For Shrink, there's this guide, https://www.videohelp.com/guides.php?link=666 and a few more in 'All Guides' to the left. Just search for the tool 'DVD Shrink' in the drop down menu.

When you start up Shrink, just select 'Open' in the file menu and then select the Video_TS file that FAB ripped for the movie. With Hitch, I used 'Analysis' and then 'Re-Author', then just the main movie, no subtitles and just the AC3 5.1 audio track for best quality.

Thanks guys for your suggestions. I did try with DVD Decrypter and also my favourite DVD Shrink when it was playing up originally. I just downloaded the DVD Fab Decrypter, and when I installed it it came up with a Fatal Error message with a blue screen saying it had shut windows down to save it causing any damage to my computer and it was dumping all my physical memory drives well so it said. I shut the computer down and tried opening the program again and it said the same thing. So I don't know what is going on there but I'll just keep persisting and in the mean time try downloading one of the other suggested programs and hope that works.

What exactly does the message say ? It will be a STOP message which will be formatted along the lines of STOP_{SOME_FORM_OF_ERROR} then a list of memory locations. Write it down and post it here and you might get better help.

'cyclic redundancy error' sounds more like a faulty media issue than any new copy protection.

Up until about 8 months ago, your assessment would have been absolutely correct. However, there are at least two new forms of copy protection that have appeared recently that can cause DVDShrink to give the "CRC - Cyclic Redundancy Error."

"Hitch" is DEFINITELY on the list of DVDs that will cause DVDShrink to report this error. The others all seem to be DVDs that have either Sony ArCCos copy protection on them, or else the protection that uses the "running boy" or "jumping boy" or some derivative (structure protection errors).

(NOTE that not all of these new discs cause the Cyclic Redundacy error in Shrink; some of them cause Shrink to just quit and shut down; some of them cause other errors -- "Exception occured" ; "Invalid DVD navigation structure" ; "Failed to open file VTS_XX_X.VOB" ; "Error Code Out of memory.")

So, in this case, he definitely needs to try a different ripper.

Formerly, the CRC-cyclic redundancy error was almost always an indication of dirty media, or scratched media, or damaged media. Not any more, though.

Below is a link to many of the DVDs that are likely to cause the CRC Cyclic Redundancy Error in DVDShrink, even if the disc os undamaged:

Hi All
I got to play around with dvdshrink last night and I am abit confused. I removed all the unwanted audio , replaced the extras with a still picture and I noticed the compression % climbed up say from 56 to 67%. Isn't the % be decreasing as I removed unwanted extras and audio format? I would prefer to keep the video as good as the original.
Many Thanks

^
It means that the DVD will be 67% of the original,it's compressing 33%.
BTW...make sure to use Deep Analysis.

[jtoolman2000]

100% mean no compression. 80% means 20% and so on.

Many Thanks

i ripped with hitch with dvd decrypter and used dvd to shrink to chrink it and then burned it with decrypter. i have done all of my 200+ like that except layer cake that gave me a problem the other night. i used dvd fab for that. i have ripped several with dvd decrypter that people here said was giving them trouble.
