Problema: mi grabador de DVD no graba

Hola a todos.
Tengo un problema: desde hace un par de semanas mi grabador no graba, no se que le pasa, pero cuando lleva un 15-25% mas o menos me da un error de escritura, aqui os dejo el error que me da:

Gracias de antemano!

mi madre ,vaya rollo...yo de codigos no entiendo nada pero si la grabadora no está averiada yo lo que haría sería reinstalar nero borrando antes cualquier rastro de él (registro,archivos de programa, datos de programa etc...) y despues intentar actualizar el firmware de la grabadora.

Saludos, puede ser cualquier cosa: lente sucia, desequilibrada o problemas de software. Intenta probarla en otro ordenador para descartar los problemas de software. Ábrela (si sabes) y limpia la lente. Espero que te sirva. Saludos a todos.
