Bonjour la liste, j'ai fait hier l'acquisition d'un graveur de CD/DVD Plextor PX-708A. La version du firmware est la (1.07), la machine où ce graveur est installé est un duron 900 Mhz équipé de 450 Mo de RAM. Un debian sid tourne dessus. Ce graveur est censé gravé en 40X et malheureusement ce n'est pas du tout les résultats que j'atteins. Avec mon ancien graveur (Ricoh 12x) je n'avais aucun problème. Mais avec le nouveau j'obtiens une vitesse moyenne de gravure de 3X :-/. J'aimerai donc savoir ce qui peut influer sur les performances à ce point. Pour plus d'informations, je vais vous paster la sortie d'un cdrecord et mon fichier de config:

Je ne comprend absolument pas d'où mon problème peut venir, ma machine est-elle trop lente ? Dois-je passer un paramètre approprié à la ligne de commande ? Merci pour votre aide. Bonne journée. -- Nicolas Cavigneaux | GPG KeyID : F0954C41 [EMAIL PROTECTED] | http://bounga.ath.cx
