Ripping Inside Out 2

[SljivovitzDino]

Hi all

Come across a weird issue - I am trying to rip Inside Out 2 to MKV and am wondering if I have this process right.

The disc will open in MakeMKV fine, and you can select the movie and begin ripping, it will get to about 50% and fail. You can select any language version and the same thing happens - it will bomb out at about 50%.

You can however, copy the entire disc contents (Pioneer UHD) in to a Windows directory using plain Explorer, this copies across without issues, that is, there doesn't seem to be any retries or delays, it just copies across. For the purpose of this post, I copied the contents in its entirety to G:\Test\INSIDE_OUT_2.

I decided to try the workaround which entails creating the discatt.dat file:

• Start MakeMKV and insert disc into drive

• Select File > Backup

• Uncheck Decrypt video files

• Specify the output directory: G:/Video/backup/INSIDE_OUT_2

• Click OK to start the backup, as soon as files are written click Stop (as discatt.dat is the first file written as it's what we're after.)

• Copy discatt.dat from G:/Video/backup/INSIDE_OUT_2 (MakeMKV backup) to G:\Test\INSIDE_OUT_2 (original disc copy)

• Restart MakeMKV and open files: Select File > Open files

• Navigate to: G:\Test\INSIDE_OUT_2 and select discatt.dat - Click Open

• Begins its processing and then fails with:

MakeMKV v1.17.6 win(x64-release) started
Debug logging enabled, log will be saved as C:\Users\matejic/MakeMKV_log.txt
Opening files on harddrive at G:/Test/INSIDE_OUT_2
Loaded content hash table, will verify integrity of M2TS files.
Saved AACS dump file as C:\Users\matejic/.MakeMKV/MKB20_v77_Inside_Out_2_B13C.tgz
The volume key is unknown for this disc - video can't be decrypted
DEBUG: Code 0 at g1G,9/u[_c:!rg}]:213132721
DEBUG: Code 0 at g1G,9/u[_c:!rg}]:121263084
Failed to open disc

Now I know I can submit the dump file (for which I will), however, I was able to decrypt and being ripping earlier when ripping direct off disc, meaning the volume key should be known - or should it? Am I performing the above steps correctly? What could be happening here?

Thanks in advance.

As it is a UHD I could imagine, that Bus Encryption is a thing with this disc as well.

You can circumvent this by first opening the disc with MakeMKV (as in let it examine the disc to the point where you select, what you want to rip). Then you can close MakeMKV or keep it in the background. Now when you make a copy via File Explorer Bus Encryption is disabled, until the tray is opened again.

OK got it.

So, first step is to unlock encryption at the bus level - which the drive handles, then I guess the second level to unencrypt the actual video.

So that worked, as in I was able to open the files and create MKVs. However, I it still failed with a M2TS hash check error.

The drive is fairly new, so its probably a dud disc.

I will attempt this on a second drive, and also with a typical straight out rip to see if the error is different.

Wash the disc with liquid soap and warm water. Dry with a paper towel. Wipe with a microfiber cloth as used for cleaning glasses.

UHDs have very often an invisible film that makes them hard to read. Even if brand new.

That is a good point - I will try cleaning as you suggest.

As a side note, the Pioneer ran through reading the disc contents kind of slowed down mid way (on Windows Explorer copy) and then completed. The LG and ASUS drives got mid way re-tried several times and eventually bombed out with a failure to copy.

Just to close this out - in the end cleaning didn't work. I had it replaced and the replacement worked a treat.

As an aside, I did notice that the original disc did have a mark right along the edge, while the replacement did not. No idea if this was the culprit.
