try going into common settings - av-codec - switch everything to software - restart dvdfab and retrloopy converting your
movie again and see if it still fails.

Hardware accelleration was already not activated.
But I found a solution...
Before going the virtual machine route I had DVDFab running on my Mac using Codeweavers CrossOver. But because I also use other software for which I couldn't find an alternative for Mac I decided to run Windows 11 in Parallels.
i installed the latest version of DVDFab in CrossOver and the conversion/compression of the movie to BD25 went without a hitch.
So the problem might have been the ARM version of Windows or the x64 version of DVDFab running on it.
But, as stated, the issue is resolved. I will stick with using CrossOver when running DVDFab on my Mac.
I know thknows also a Mac version, but it's re-encoding results are inferior to those of the Windows version.
