Una cuestión técnica, para variar. Tengo una cámara de las que graba en DVDs que da problemas. De entrada no me deja finalizar los discos, siempre que lo intento me dice que ha ocurrido algún error sin más información adicional.

El tema es que tengo algunos DVDs (DVD-R) que grabé en vacaciones y cuya información me gustaría recuperar. Lo curioso es que en la cámara se ven dichos vídeos bastante bien, pero no se pueden ver en ningún otro medio: lo intenté en mi ordenador, el de mi compañera y en dos reproductores de DVD con el mismo resultado, se creen que son DVDs vacíos.

Si miro uno de ellos en mi ordenador con el dvd+rw-mediainfo, esto es lo que obtengo:

Por lo que entiendo que los datos están ahí, por eso la cámara puede reproducirlos, pero ningún otro medio parece ser capaz de hacerlo :-?

He probado con el dvdisaster en mi Kubuntu sin éxito alguno, de hecho se niega a leer el DVD siquiera ("Reading finished: 1 unreadable sectors"), no obstante el hecho de que los datos estén ahí y que incluso la propia videocámara sea capaz de reproducir los vídeos almacenados, me llevan a insistir con esto porque estoy convencido de que tiene que haber alguna manera de recuperarlos.

Cualquier ayuda en este sentido será bienvenida.
