Getting this error for one of my blu rays. Any ideas? Disk plays fine in standalone BD player. The movie file does not seem to save.

Here is log:

Try gently cleaning the disc.

Unlike your blu-ray player, MakeMKV tries to verify that it correctly reads all the bits from the disc. It won't save a file that it can't correctly read. There's no way to disable this feature.
