Ich habe eine DVD, die mit einem DVD-Recorder/Player erstellt wurde. Ich versuche, die Dateien davon zu extrahieren, damit ich das Filmmaterial bearbeiten kann.
Mein Problem ist, dass ich die DVD nicht lesen kann. Sie wird unter Windows und OS X als leeres Laufwerk erkannt. Linux findet das Laufwerk nicht, um es zu mounten. Die DVD kann auf einem eigenständigen DVD-Player (ich habe es mit einem von Toshiba versucht) problemlos abgespielt werden.
Da ich die Festplatte mit Ubuntu nicht mounten kann, gehe ich davon aus, dass sich auf der Festplatte ein Dateisystem befindet, das nicht gelesen werden kann. Gibt es da draußen Pakete, die ich installieren kann, um dieses Dateisystem zu lesen und die Daten abzurufen?
EDIT: Nach dem Ausführen vlc /dev/sr0von dmesg wird folgendes angezeigt

Auf dieser Grundlage würde ich ddes in eine ISO- oder IMG-Datei umwandeln. Ich bin mir jedoch nicht sicher, ob das die E/A-Fehler behebt.
