Hey folks,

I've been burning through my UHD collection of 100+ disks and this is the first issue I've run into. I can back up the disks just fine, but decrypting runs into "volume key unknown for this disk". 3 of the UHD disks - Skyfall, Spectre, and Casino Royale all failed but were able to be backed up successfully (encrypted). Quantum of Solace actually decrypted just fine. These were out of a brand new box set I picked up at BB this week. Spectre was a nightmare to get to read, even fresh out of the box with an alcohol cleaning it failed over and over right about halfway through until I got lucky.

I submitted the dumps to svq@makemkv.com as per the UHD FAQ here a couple days ago but still no joy in decryption - what's the average wait amount of time for those to get updated? Are there any recommended alternatives to get these ripped if there's a chance it's impossible to update?

Interestingly these must be new versions or something because there were previous threads here about this set needing keys and getting them updated many months ago.

From the same FAQ...

I submitted a dump, how long does it take?
Once submitted, the turnaround can be pretty fast, between 12 to 48 hours.
When you submit a dump, ensure that:
- You are using the latest version of MakeMKV
- You are using a LibreDrive-enabled drive (be it "friendly" or "official", but it must be LibreDrive enabled)
- You have "Enable Internet access" enabled in Preferences (in the General tab)
- You are opening the original disc (not a backup, not ISO, etc)
- You are opening the disc using a real disc drive natively (no elby clonedrive, no vmware, no dvdfab or discsoft virtual, etc)

Note: sometimes Mike is busy & it can take longer

I see a movie discussed in the forum, but MakeMKV won't open my disc.
There are multiple versions of UHDs for each movie (countries, retailers, rentals) and there may be multiple keys for even the same version, so it's possible that your particular disc isn't decrypted yet. Submit the dump file!
