hola,

pues eso, el maldito buffer underrun aqui dando la lata, que no se que puede ser.
La verdad es que hace poco me iba un poco mal, tardaba mucho en grabar los DVDs. Pero le actualice el firmware y ya tiraba otra vez bien, hasta que la semana pasada dijo que buffer underrun y ahi estamos.

aqui dejo el log del nero, por si alguien sabe que puede ser
Muchas gracias por adelantado
