While attempting to save space on a backup drive, i removed non essential.m2ts files from a full disk backup. I inadvertently deleted a .m2ts that was part of the movie. While processing the backup with MakeMKV., the .mkv was created even though all the m2ts files listed in the playlist were not present, makemkv did not complain it just created an imcomplete file. It plays fine till it get to the missing segment and just stops.
Mike, can you add a check for multi segment playlists that checks that all parts are present before processing?
