Eu tenho um DVD que foi criado em uma caixa de gravador/reprodutor de DVD. Estou tentando pegar os arquivos dele para poder fazer a edição de vídeo da filmagem.
Meu problema é que não consigo ler o DVD. Ele é detectado como um disco vazio no Windows e no OS X. O Linux não encontrará o disco para montá-lo. O DVD reproduz perfeitamente em um DVD player independente (o Toshiba foi o que eu experimentei).
Como não consigo montar o disco com o Ubuntu, acho que existe um sistema de arquivos no disco que não pode ser lido. Existem alguns pacotes que eu possa instalar para me dar uma chance de ler este sistema de arquivos e extrair os dados?
EDIT: Depois de executar vlc /dev/sr0o dmesg mostra o seguinte

Com base nisso, meu palpite é colocá- ddlo em um arquivo .iso ou .img. Não tenho certeza se isso ajudará nos erros de E/S.
