Un problémé de gravure avc nero7 Ultra editio

Bonjour,
J'ai un probléme pour graver des CD depuis une semaine, à chaque fois que j'essaye de graver, et juste au debut de la gravure ça s'arrête et je reçois un message d'erreur, d'ailleurs je joins au message le rapport d'erreurs.
Merci d'avance de m'apporter votre aide
