Extracting DVD tracks

To extract DVD tracks identify the actual tracks first:

HandBrakeCLI -Z "Very Fast 1080p30" -i DVD.ISO -o test.mp4 -t 0 |& grep -e title -e "+ duration"

After that run the following command with the wanted title number:

HandBrakeCLI -Z "Super HQ 720p30 Surround" --audio-lang-list deu -i DVD.iso -o filename.mp4 -t <track#>
