1) All three movies proved to be an unpleasant experience where creating an mkv file direct from disc (all three movie discs) part way through failed out as if the discs were damaged. The movie is 1 m2ts file on the disc.
2) If the disc is backed up so the entirety of files is copied over to a drive, it slows down at a given point but manages to work through it. From the back up on drive, I am able to make an MKV file of just the movie with the video + single highest level audio stream. (US version the subs are hard coded while UK version they are a separate - not forced.)
3) The price is very good at the time for UHD, Blu Ray and digital for all 3 movies ($20.00) and the packaging looks nice but its miserable for removing each disc. I suggest being ready to move them over to a better case and take the above into consideration. I am using the external case w/ASUS burner with the correct firmware.
