Hi,

I'm unable to extract title #8 from a commerical DVD. Below is the MakeMKV output:

Title #8 (0:44:18) was skipped due to navigation error
Failed to open disc

Any help is appreciated!

I was able to use Handbrake instead to open/extract the title. Same for 2 other titles that MakeMKV displayed "navigation error" with. I don't know if this is relevant, but MakeMKV displays an error when opening all the Law & Order DVD discs complaining that the discs were created using Jack the Ripper. These are commercial DVDs sold in a collector's box by a large, physical store, so I assumed this error was a false positive.
