Pb gravure DVD

Bonjour,

Je n'arrive plus à graver des dvd avec nero7 ou avec n'impore quel autre programme. j'utilise des dvd-rw et tous marchait bien jusqu'à aujourd'hui. Par contre j'arrive à:
-lire des CD
-graver des CD
-lire des DVD
-ET JE N'ARRIVE PAS à GRAVER DES DVD.

Je possède un lecteur Pioneer DVD-RW DVR K17-RS.

La mise à jour firmware n'est pas possible pour le moment car lecteur est encre trop récent.

Description précise du problème:
Lorsque je veux graver un film sur DVD avec néro, tout va bien pendant l'encodage et au
moment où la gravure commence le problème survient; ça met Echec de la gravure.

J'en ai aussi profiter pour en faire un log:
