Ken Burns JAZZ (2001) Disk 3

[psycoperl]

Dear All

Hope that you had a happy and healthy 2025.

I was encoding Disk 3 of the Ken Burns JAZZ Documentary as a MKV file and got the following. I tried this multiple times and without any success. Disks 1 & 2 encoded without issue. Any guidance would be appreciated.

To provide additional context, I tried this using my Apple SuperDrive and a BluRay Player on my MacBook Pro (M4 Pro)

I don't think I've seen an error like that before. Are you trying to create .mkv files directly from the optical disc or from a backup?

I was working from the physical media.

You could try using MakeMKV to create a decrypted backup of the disc (click the icon of the yellow folder with the green arrow on MakeMKV's first screen). For a DVD that'll make a .iso file (assuming the optical drive can correctly read the disc all the way through).

You can then open that file with MakeMKV again to try to create .mkv files. If that doesn't work, you should be able to use MKVToolNix GUI to open the .iso file and try to create .mkv files that way.

Separating the reading of the disc from interpreting the structure and content of the disc sometimes works. Sometimes disc structure that confuses MakeMKV works in MKVToolNix.

Working from the Backup:
MakeMKV v1.18.2 darwin(arm64-release) started
Optical drive "DVD+R-DL HL-DT-ST DVDRW GX40N RQ00 KW9D82E4542d" opened in OS access mode.
Backing up disc into folder "/Users/gmh/Movies/backup/JAZZ_03.iso"
Backup done
Using direct disc access mode
Title #1 was added (67 cell(s), 1:49:35)
Title #2 was added (1 cell(s), 0:00:10)
Title #4 has length of 7 seconds which is less than minimum title length of 10 seconds and was therefore skipped
