I've converted hundreds of movies using version 1.5.8 of MakeMKV, from two years back. I have never had an error, not once.
The ISO files are based on DVD-Shrink ISO's where the DVD is simplified (no menus, no extra tracks, etc). Again, using 1.5.8, there has never been a problem with this.
Most often, I do this using the command line:
MakeMKVcon64 mkv iso:F:\MyDir\MyMovieName.iso 0 F:\MyDir\MyMovieName
Last week, I upgraded to v1.7.2. Now, I get "Navigation Errors" for *every* .ISO that I attempt to convert.
To confirm this issue is related to newer versions, I have attempted to convert .ISO's that I previosuly had converted with MakeMKV 1.5.8. There was no problem in the original conversion, but now, using 1.7.2, I get the Navigation Error, using the same command line.
I attempted to downgrade, but now that I've had the new version installed, it claims I cannot use the old version any longer.
Here is an example of the error:
I've tested in both the console and GUI version, same results in both cases.MakeMKV v1.7.2 win(x64-release) started
Title #0 (1:32:23) was skipped due to navigation error
Failed to open disc
Thank you in advance,
