Longest track: 14
Lorsque je sauvegarde le titre 14 avec dvdbackup -i /dev/sr0 -T 14 -o ~/Videos, je ne reçois qu'un fichier VOB de 103 Mo inattaquable.
Serait-ce une sorte de protection contre la copie ou un autre endroit où chercher le problème? Le DVD lui - même est regardable avec vlcou mpvlecteurs vidéo.
J'ai également essayé de sauvegarder l'intégralité du DVD, et cela entraînait 23 Go + et comptait, alors je l'ai annulé.
