Questão Como confirmar o erro do setor em um DVD de vídeo


Se um DVD pula por volta das 21:00, existe alguma maneira de relacionar isso às mensagens do kernel?
Eu gostaria de saber se o formato de DVD é padrão o suficiente para comparar o tempo que o filme pula com os setores mostrados abaixo? Ou eu só tenho um leitor de DVD de baixa qualidade?

Não responde exatamente a pergunta, mas você pode tentar rasgar o disco com o seu programa de escolha e, em seguida, inspecionar o log do programa - é provável que você receba erros de leitura que provavelmente identificarão o setor. - user55325
