Hola, tengo un problema con mi grabadora Sony DVD RW AW G-170A, que no me permite grabar un DVD+RW. Cuando lo intento grabar con NERO me sale el siguiente mensaje: Error al formatear el disco, No se ha podido realizar el inicio de Disc-at-once, El proceso de grabación ha fallado a 4x. He reinstalado el NERO pero me sigue dando el mismo error, tb lo he intentado con otros programas y nada. No sé que puede pasar, aquí está el log, a ver si alguien puede echarme una mano o darme alguna pista:
