Hi,
I got a rather unusual bug with AnyDVD (currently I'm using version 6.3.1.2). When i copy a file from an HD DVD or BD to the HDD and then compare it with another copy of the same file, they in fact differ. This also happens if I make an image of the disk and another image of the disk and compare them, they still differ. This happens quite often even though not always.
Then when I copy the file/make the image a third time it sometimes happens that this copy is equal to the first or the second. Some disks tend to behave like this some other tend to deliver different data each time I read the file.
I've done a File Comparison over these files so that I could see the actual difference. It seems the differences have always the length of 24 bytes. That's a little strange because the block size of the AES encryption used for AACS is 192 bits... exactly 24 bytes. Could it be the decryption algorithm has an error?
The FC output is attached. Note that this one is from the German release of "Into The Blue" BD from the file BDMV\STREAM\00065.m2ts
