I have tried to back up several Bluray Discs. I'm currently using 18.104.22.168 beta.
I can back up the disc "successfully."
If I try to play the main movie, it works. HOWEVER, if I try to play the folder as a BD folder, I get a black screen. This also happens if I convert to an ISO and mount it on a virtual drive as a BD disc.
Example: The Bank Job (region 1/USA)
I point to the folder. The back screen loads and the INFO screen reads:
Title 001/001 Chapter 000/000
I have tried the same with at least 5 discs and they all produce the same issue.
