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 o� ce graveur est install� est un duron 900 Mhz �quip� de 450 Mo de RAM. Un debian sid tourne dessus. Ce graveur est cens� grav� en 40X et malheureusement ce n'est pas du tout les r�sultats que j'atteins. Avec mon ancien graveur (Ricoh 12x) je n'avais aucun probl�me. Mais avec le nouveau j'obtiens une vitesse moyenne de gravure de 3X :-/. J'aimerai donc savoir ce qui peut influer sur les performances � ce point. Pour plus d'informations, je vais vous paster la sortie d'un cdrecord et mon fichier de config:
