necesito ayuda por favor tengo demasiados posavasosn creo q hasta puedo poner un negocio!...

mi grabadora es una lg gce-8520b 52x24x52x, hace unas semanas mi quemadora ha comenzado a fallar y graba mal las pelis que me bajo. Utilizo el nero 5.5.10.20 .

He programado la medicion de velocidad y la simulacion, las que se realizan sin inconvenientes. me he percatado que al finalizar la simulacion al 99%,  el bufer de lectura cae paulatinamente hasta el 0% , cuando se inicia la grabacion, el bufer de lectura y del grabador no marcan nada!, luego de un par de segundos el bufer de lectura se normaliza , pero la grabacion q ya esta en 2% se congela por unos segundos, mientras, que el bufer de grabacion tambien se congela en 94%, baja inmediatamente a 21% y luego sube a 94%.

El proceso de comprobacion falla y me sale esto en el log:

¿ a que se debe esta falla?
algunos dicen q puede ser q la lente este sucia
otros q falla el firmware
¿ un cd limpiadr es una buena opcion?
he buscado el firmware para mi quemadora pero no lo he encontrado, ni en la pagina de lg!
