The Powers That KEYDB cannot read all of the information needed from a TGZ dump that was created by a Pioneer drive. However, sometimes that information can still be enough.

What is the full name of your TGZ dump file please?

I'm also having issues with both UK UHD 4K releases of TRON and TRON Legacy. What all can I do to assist in getting these added to the database? I'm not to dump files and all that in relation to makemkv, is there a guide I can follow?

Providing a dump file for UHD 4k release of Tron Legacy to assist with updating the KEYDB file.

I received a "The volume key is unknown for this disc - video can't be decrypted Failed to open disc" error using the latest version of MakeMV and KEYDB.

MKB20_v77_Tron-_Legacy_EDFB.tgz

Link to the tgz file:

You'll need to zip up and link the MKB_RO.inf file in the AACS directory for that disc.

Unless the Media Key for that disk is already known?

I'm sure it is but you have to have the MKB_RO.inf to validate that assumption.

You can also validate a Media Key by checking whether MK (x) VID generates a VUK that can successfully decrypt the Unit Keys. This assumes that the TGZ contains a kv.dat to validate the Unit Keys against, of course.

Yup you can. My code does not.

I was able to rip my copy, here is how it layed out: https://thediscdb.com/movie/tron-legacy ... eelbook-4k
