Data error (cyclic redundancy check) Problematic Movies with ARccOS™:

Problematic Movies with ARccOS™:
DVD Shrink can't backup movies with Sony's DVD protection system ARccOS™. Affected movies are mostly US region 1 DVDs - but also some region 2 DVDs. The problems you notice are:
Data error (cyclic redundancy check)
DVD Shrink will just disappear
Error code "Exception occured"
Error code "Failed to open file - The system cannot find the file specified"
Error code "Invalid DVD navigation structure"
Error code "Out of memory"
Windows system error
Your PC is freezing
Here is a list of some of the DVDs that are known to cause problems with DVD Shrink and solutions to your problem.
The best solution is to first use DVD Decrypter ver 3.5.4.0 to transfer the DVD to your hard disk and then you can use DVD Shrink without problems.
Movies that needs a PSL2 file with DVD Decrypter ver 3.5.4.0
Some recently released Sony ARccOS™ copy protected DVDs have a modified version of ARccOS™ on them and are not fully supported by DVD Decrypter version 3.5.4.0 as DVD Decrypter is not updated any more. You need to use an additional file that will solve this problem.
If you try to use DVD Decrypter without such a PSL2 (=Protected Sectors List version 2) file - you will get an I/O error in DVD Decrypter. This PSL2 file tells DVD Decrypter which sectors that are bad and that it shouldn't try to read. Instead the program inserts a 'dummy' sector. This dummy sector is a black video stream and it is not something you will see in the final backup.
