So I figured if it will rip without errors in Anydvd I have a good disc if not I returned it. I'm unable to watch all the movies in the short time that I can return for exchange at BB. It failed and I didn't know if it was due to a bad disc or not. I had all kinds of problems when I tried just processing the star wars saga off the disc using makemkv. I started using makemkv just for the few UHD movies I was buying. I use anydvd because that's how I learned to do it. With 1.15.4 I was able to open the ISO I ripped earlier process the MKV of RotJ and had no specific errors but did say there are some sync errors. You may very well have been on to something. If that can be a source for MakeMKV to work from, I think you could just use 1.15.4 and make a new MKV file from your ISO. I don't know exactly how AnyDVD works, but presumably the ISO you made is just a representation of the bits on the disc in an alternative form. In this case, if you had created a backup with MakeMKV with version 1.15.3, you could make a new MKV file with 1.15.4 and gain the benefits of the fixes and changes in 1.15.4.

m2ts files to figure out which one is English (since the *.m2ts filenames correspond to the segment map numbers).

In the case of things like a Pixar film with the typical 3 copies of the movie, I can examine the individual. In the case of movies with title obfuscation I'll keep the backup until I watch the movie and verify the rip, otherwise I usually delete the backup.

I then make a second 'final' MKV file to keep. I label commentary tracks and forced subtitles, etc. The first one I uncheck the languages and subtitles I'm not interested in. Doing it from fast storage means it typically only takes 2 or 3 minutes to create the MKV. (I would create an encrypted backup in the rare case a key isn't yet available.) However, I do usually use MakeMKV to create a decrypted backup to a hard drive first. I have not used AnyDVD (I'm on a Mac) so I can't comment about the value of having an encrypted ISO.
