Hi, I've just started backing up blu-rays using CloneBD for mainly mp4s. I am reading any of the tutorials written here regarding removing cinavia. Some tutes do not open anymore. I wanted to learn how to remove it whenever I might come across one of these disks. After testing the disk in CloneBD, and ticking remove cinavia in anydvd, I tried removing it from the Jason Bourne dvd to a mp4. Tried many times but the tute didn't compare with what I was seeing. Then I clicked on the Folder icon instead of mp4, I then saw the correct page was there but then clone crashed with an error. I had already made the mp4 before I found out the disk had cinavia on it but when I tested the mp4, it played fine anyway. I played the mp4 on a usb 3.0 flash drive in my stand alone blu-ray player on the tv and cinavia was not on it. Does cinavia not affect mp4s? Also while using CloneBD should I keep cinavia ticked in any dvd by default? Thank you for any information you can provide. I don't quite understand.
