I tried, but its not working. I used MakeMKV, and i clicked the Backup Disc button, and it started ripping my movie. File size is over 40GB, but there are 3 folders: AACS BDMV CERTIFICATION Each folder has subfolders, some more than others. I went to Handbrake, and in the BDMV folder, there is a folder called STREAM, and after opening it, there are over 50 files ranging from 800KB to 5.55GB. I used to biggest GB file, but it didn't work. Handbrake kept saying: "No Valid Source Found" I tried a lot of different files looking for the main film file to use on Handbrake, but I can't find it. Did I do something wrong? Has anyone ever experienced the same problem and was able to solve it? Thanks in advance.
