Any idea about the checksum differences? C2 errors were fixed both times, but the checksums differ.

AnyDVD detects CSS there (VLC doesn't, though):
MMC-6 says
00h indicates there is no such data and 01h indicates a specific data structure for CSS/CPPM exists, and 02h indicates a specific data structure for CPRM exists, and 10h indicates a specific data structure exists for AACS with BD content. All other values are reserved.
Btw, does plextor also output 0xc4?

Video player uses these keys to decrypt data. Key info doesn't need for user generally.

Try to use /c2 val2, val3, val4.
Code: Select all
/c2 Continue reading CD to recover C2 error existing sector
val1 value to reread (default: 4000)
val2 0: reread sector c2 error is reported (default)
1: reread all (or from first to last) sector
val3 first LBA to reread (default: 0)
val4 last LBA to reread (default: end-of-sector)
val3, 4 is used when val2 is 1
example
Code: Select all
C:\Users\HTPC\Desktop\Disc Image Creator\Programs\DiscImageCreator.exe cd H ISO\BORDER_DOWN\BORDER_DOWN.bin 32 /c2 20 1 320000 332000

I have problems with safedisc 2.9 discs sometimes, it seems they have some type of weak sectors towards the end of the disc. They get no C2 errors, but get EDC/ECC errors after descramble and I have to manually redump those sectors many times in iso buster after performing a seek to 150 to get a good dump of them.
So far two discs have this problem, disc 3 of original Splinter Cell version, and Need for Speed Hot Pursuit. I wonder if anyone else has encountered this?
CSS seems OK now for the discs I tested.
If RapidCRC is not present with test version, hashes are not calculated. Maybe forget I suggested this as the tool has no command line version.
Can you remove the 4 spaces from produced dat files , I have to manually remove them always when submitting dump hashes.

But the DIC dumps aren't decrypted and we need to convert the CSSKey keys to AnyDVD/VLC format somehow to use the images.

I used to have problems with this disc. I think it uses weak sectors too. I had to manually zero out scm file in some places and then descramble manually to get correct data...

Decrypted image should be preserved in the db? To decrypt the DVD-VIDEO / BD-VIDEO / Wii / PS3 is legal act or not?

VLC can play the encrypted images, because it has libdvdcss.
Btw, Is libdvdcss legal or not? And dolphin (wii emulator) decrypts the aes of wii disc images, but RPCS3 (PS3 emulator) doesn't decrypt the aes of PS3 disc images. If decrypting is illegal, dolphin is illegal? If decrypting is legal, why RPCS3 doesn't support the decrypting?

Should be 0xc4 also recognized as CSS? Or 0xc4 is a firmware bug of AD-7200A?

The latest test version is giving broken cue files for non-multisession discs.
Confirmed the last version is too on this computer, other tools are fine. Must be some bug that is making it think the entire track is pre-gap.

I don't know, you're the programmer
But it has also misdetected the regions: 1 2 3 4 5 6 7 8 instead of 2 5.

We don't need the decrypted images, we need to know how to convert the keys from dump_CSSKey.txt to the AnyDVD/VLC(libdvdcss) format. You can use the encrypted iso images, but you need the decryption keys to play them.
Here are 2 DVD logs attached and that's how the keys in AnyDVD/VLC/libdvdcss format should look like:
Every encrypted file has its own key. Please, find a way to convert dump_CSSKey.txt to the libdvdcss keys format
libdvdcss is open-source -

Does it mean you want to get the titlekeys? If yes, I already supported to get it.

If no, I don't know now what kind of format 'libdvdcss keys format' is.
