I ripped this bluray (When We Left Earth disc 1) with AnyDVD ripper, and tried to mkv it with make MKV. All extras work fine, just the two main titles that fail. Any idea why?

I ripped this bluray (When We Left Earth disc 1) with AnyDVD ripper, and tried to mkv it with make MKV.

MakeMKV is fully capable of decrypting/ripping virtually all standard DVDs and BluRay discs.

Therefore, there's absolutely NO REASON to use AnyDVD for your MakeMKV projects...

looks like corrupted input, but exact cause is unknown. do you see the same error if you open disc without anydvd?
