I am backing up this BD from The Masters of Cinema Series and creating a .mkv file. The soundtrack is significantly off in its timing for both the Italian and French tracks. The English subtitles also didn't show until I used the "force" option. Before the film starts there is an informational insert regarding the creation of the disc that I think is throwing the audio off. Also, on some of my attempts the video was stuttering and slow after I would skip ahead and then resume playing. Of note, the disc plays fine on the computer I am using to make the copy (using Leowo Player). Any insight? Thanks!
