I have been trying to decrypt The Martian Extended Edition now for a few days with no luck. I have a proper drive and the key has been released for that disc, so I don't have the best idea as to what's gone wrong.
However, today while trying to make a back up of the disc, I noticed that there was a "DFEX" directory in which there were a few files. I didn't really think anything of it until I looked up the type of file present in that directory: a .scav file. I looked that extension up and it appears to be a disc first aid... and then I realized that if you were to say DFEX aloud it sounds like defects. I looked back at the MakeMKV program and saw that there had been errors spitting out like:
Code: Select all
DEBUG: Code 0 at h(BZV-JrIjt/1~;5p:121266856
I did a little bit of testing on this theory. I cleaned the disc thoroughly with some isopropyl alcohol and it backed up the disc no problem. However, I could still not decrypt it even thought there is a key out there for The Martian Extended Edition. (Anyone have ideas as to why it wouldn't decrypt?)
I haven't had any luck decrypting The Revenant either, so I checked to see if it had a DFEX dir and it did, and yet I made a backup of The Revenant no problem. I couldn't decrypt it though.
Arrival is another movie that I can't decrypt and have a key for yet it won't decrypt. It backed up just fine though.
So... what does it mean if there is a DFEX dir?
