Como confirmar o erro do setor em um DVD de vídeo

Question

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