Hi mopar_mudder, I had the same/similar issue yesterday. I purchased the 4K remaster of Punisher, it came with a bluray version of the movie and since I do not have a 4K reader in my PC I ripped the bluray version of the movie. When I put the disk in DVDFab 10.2.1.7 it wouldn't add it to the task list. The volume label of the disk showed up in explorer so I expanded the directory tree and dragged the BDMV folder into the window and it worked that way. That is the first disk that I have had to do that to.
Dead Eye
Tried that and still nothing. Draging the BDMV folder over DVD Fab just sits there and does nothing. Also updated to newest V11 today and no change.
This is getting a little old.
