New Titles

[Rotd1]

The following won't open.

Blood on Satan's Claw
Witchfinder General.

Log attached.

[Woodstock]

No logs seen.

What error messages are you receiving? "Won't open" is very ambiguous without the logs. You do not have to "attach" them, just post them in the message.

[Rotd1]

The error message on both discs says " The volume key is unknown for this disc - video can't be decrypted
Failed to open disc".

I've attached both .tgz files this time, thanks.

[Woodstock]

OK, that general error message says that MakeMKV hasn't got the database with the decryption key for those disks. Assuming you are getting updates (that would be listed in the log), you should submit the .TGZ files that were generated to svq@makemkv.com, so that they can be created/added to the database.

There won't be an acknowledgement that it has happened; the rip will just "work" once the keys are in place. That can take a day or two.

[Rotd1]

Thank you very much.

[Rotd1]

I checked again this morning and still no joy with these two titles. Are they proving to be problematic?

[Woodstock]

Are you still seeing the error message about not being able to download the key file? It is possible that they key has been generated, but your system is "protecting" you from it.

[Rotd1]

The error message says "The volume key is unknown for this disc - video can't be decrypted - failed to open disc".

When you say that my system is protecting me from it, what does that mean?

[Woodstock]

You haven't posted a log yet, but I'm guessing it says something like:

Automatic HK downloading is disabled or failed.

somewhere along the log. That says it cannot download keys, which will prevent you from accessing anything your system doesn't have they key for yet.

Are you seeing that message?

[Rotd1]

How do I find the log?

[Rotd1]

Found it.

[Woodstock]

You should submit the two files mentioned to be processed.

MKB20_v77_Witchfinder_General_UHD_49E8.tgz
MKB20_v77_Blood_on_Satans_Claw_UHD_D604.tgz

The email address is the fastest. Then, assuming nothing is blocking access to the key server (nothing was mentioned in your logs), you should be able to process the disks when the keys are created.

If you have the disk space, you can rip the disks without decryption and decrypt them later, but I haven't bothered.

I've emailed you the .tgz files. Hope this helps.

After inserting any of the discs, I now get this -

"Automatic HK downloading is disabled or failed." usually means something is blocking you from getting the update file. This is more and more common as anti-piracy people start blocking hosts.
