I make decrypted backups of discs with MakeMKV all the time. I then create .mkv files from these backups. I don't think I've had a situation where I've successfully made a backup without errors that has then failed to produce .mkv files. Do you know if your backup was created without errors? If you ...

I think bmmomin was just saying that the failed to open message is still persisting "The volume key is unknown for this disc - video can't be decrypted". There's usually two reasons why one might get that message. There might not be a key for that disc and the dump file should be emailed ...

how can i do a protected backup with makemkv ?

On the first screen of MakeMKV, click the icon of the yellow folder with the green arrow. Make sure the decrypt box is unchecked.

There's certainly something about that disc that your optical drive doesn't like. If you want to copy the whole disc to your drive, using MakeMKV's backup function is the best way to do that. On the first screen of MakeMKV, click the icon of the yellow folder with the green arrow at the top. Make su...

Hello again,

now i have the same problem as last time.
My new purchased Blu-Ray Disc won't decrypt.

Please help me again, as last time and add it to the database.
Here are the new dump files.

Thanks a lot!

Did you also email these dumps to svq@makemkv.com?

Do different players show similar corruption? By that I mean does VLC and MPV (or whatever your favorite players are) both show a corrupted file?

Please email the dump file (the .tgz file) to svq@makemkv.com.

Also, checkout the KeyDB.
Public KeyDB Disc Submissions

Add one more to the list with the exact same error: The source file '/BDMV/STREAM/00327.m2ts' is corrupt or invalid at offset XXXXXXXXXXX The strange thing is, I was able to extract the entire disc once and ran it through Handbrake without an issue. Now I just want to save a raw copy of the main ti...

Hello . I try with the french disc but nothing works ... I download the last key but change nothing. Can you help me ? Can you copy & paste your MakeMKV log (the bottom half of the window) of MakeMKV failing to rip this disc into a post here? Seeing the log will help people figure out the probl...

Perhaps you can post a screen shot of what you're seeing?

I am a MakeMKV newbie. I just encountered the issue that I think is under discussion here... trying to rip "John Wick" from a disk that's said to be: "4KUltraHD, BluRay, Digital HD". All I wanted was the BluRay (1920x1080). There were over 200 titles listed, they were all pre-se...

MPV has a decent slow motion/high speed capability that I use with some regularity. The documentation suggests there's a video zoom, but I've never tried it.

Hello, sorry to resurrect an older topic but this is the top Google hit for this topic and I feel like it's almost giving me the information I need. I read to backup the disc with MakeMKV, then bring the playlist into MKVmerge. And I see MKVmerge is part of MKVToolNix. But when I backed up my disc ...

Hello Mike, I tried to rip the Titanic 4K UHD Blu-ray with MakeMKV v1.18.1. My drive is a Pioneer BDR-UDD4 with LibreDrive enabled. MakeMKV generated a .tgz file because it couldn't decrypt the disc. Here is the attached file: MKB20_77_Titanic_ECB3.tgz Thanks in advance for your help! MKB20_v77_Tit...

I have the movie Zack Snyder's Justice League (2021) which is too big to fit on a single disc, consequently, I have two .mkv files that make up the entire movie. I do most of my movie watching via Plex. Plex has a feature that allows for a movie to be split across multiple files. ( https://support.p...
