copying stops - Ginger Snaps UHD

[aimforsilence]

I'm trying to copy the 4K UHD version of Ginger Snaps but almost immediately nothing copies even though MakeMKV shows that it should be. Read rate stays steady and doesn't drop, the disc itself is brand new and looks flawless. The transfer just gets stuck at around 863MB copied. Not sure what to do. It doesn't fail so there are no logs or anything like that, it just stops copying data and then just sits there indefinitely.

It is often the case that even brand new discs need a gentle cleaning in order to rip correctly. Try cleaning the disc.

tried giving it a good cleaning and same exact issue anything else I could possibly try?

Does it happen only with this disc / a type of disc?

I've never had this issue with any other 4K UHD or Blu-Ray disc and I've copied a ton of different discs over the years. Usually if the disc has issues it will time out and have an error code or a log or something. This one just keeps looking like nothing is wrong but can't get past 863MB copied. I tried copying it with certain audio tracks unchecked, same issue. If I try copying some of the bonus content it works fine... real weird issue. Will try copying on a different computer next I guess.

Sounds like this disc somehow triggered a bug in the firmware of this model or something like that. (Assuming you have been ripping discs with the same drive + same USB adapter + same computer/OS.)

Btw you may want to see if the same problem also occur if you merely try to make an encrypted backup of the disc (just in case you are so "lucky" that it's just a bug in decryption or remuxing that have been triggered -- in that case you can decrypt / remux with something else later).

I was able to SUCCESSFULLY make a backup of the disc, but when I loaded the backup and tried to copy the movie again I hit the same snag. It gets stuck at 863MB

[tomty89]

Was it an encrypted or decrypted backup? If it was the former, have you tried making a decrypted one as well?

[aimforsilence]

The backup of the entire disc was encrypted. Should I try decrypted instead?

[tomty89]

Well with an encrypted backup you can only play it with a player that leverages libmmbd or libaacs. If your goal is to create an MKV remux of it, obviously you need a decrypted backup so that you can try to remux with other tool (such as mkvtoolnix) and see if things can get through.

So now you would either want to make a decrypted backup with MakeMKV from the disc again, or go straight ahead to make one with some other tool such as a libaacs frontend like https://git.golem.linux.it/matteobin/bluraybackup. I'm assuming the public keydb also has key for this disc btw.

(EDIT: Unfortunately bluraybackup assumes libbluray can only read from a disc. Therefore without at least some simple patching it cannot be used to decrypt an encrypted backup. However for at least drive/disc with bus encryption enabled, you'll need to at least open the disc once with MakeMKV so that LibreDrive gets activated before you can use bluraybackup to rip it.)

P.S. I don't really know much about the alternative BD ripping / decrypting solutions available out there that are more Windows/GUI user friendly. I heard that there's one call Xreveal (which is apparently somewhat free / freemium). To use / build bluraybackup mentioned above on Windows, you'd need to mess around with msys2 / mingw. (Or maybe WSL.) So probably you want to at least try MakeMKV first.

I was able to make a decrypted backup of the movie successfully, but when I load the backup in makemkv and try to copy just the movie, same exact issue again. I'll look into that bluraybackup command line tool you suggested, but I'm not the best with command line stuff.

If decrypted backup got through, then you don't need to bother ripping with another tool. Either there's a bug in the remuxing part of MakeMKV, or it's simply that the content of the disc is not properly authored.

EDIT: I'm assuming the disc is encrypted with only AACS but not BD+. For the former it's hardly possible that MakeMKV could have screwed up and output incorretly decrypted content. For the latter I'm less certain.

Just try mkvtoolnix or whatever that's out there that can remux m2ts / blu-ray into MKV.

This is the disc's info

Label: GINGER_SNAPS_UHD
Timestamp: 2026-03-25 23:52:05
Protection: AACS2.0/C v82
Data capacity: 91.75 Gb
Disc type: BD-ROM UHD
Number of layers: 3
Bus encryption flags: 80

not sure if that's helpful. I'm currently trying to remux the m2ts into a mkv container with mkvtoolnix, though I am worried it's going to have issues with the Dolby Vision profile... I had tried using DVDFab to remux but Plex was not happy with the HDR/DV profile... so hopefully I figure this out. I hate banging my head on the wall.

I was able to copy Ginger Snaps 4K. You just have to be Patient. It seem to stop at 863.4M like you said but if you wait about an hour it starts moving again at a slow but steady rate. I don't remember how long it took to finish but I want to say like 5 hours. This happen once before on another Lions gate disk. I don't remember which one but I let it run all night and it was done in the morning. Midway is another Lions gate with another method to thwart us but there was a way to do that one also. I grown now when I see a new Lions gate disk as to what they are going to try to do to keep us from backing up our movies to MKV.
