Salut à tous,

J'ai de gros problèmes avec K3B et un graveur PHILIPS DVDR 824P.

Le graveur fonctionne normalement sous Windows, fonctionnait tout aussi bien sous Mandrake et Debian Sarge, ce qui exclut à priori tout problème hardware. Mais depuis que je suis sous Kubuntu (Breezy) j'ai systèmatiquement droit à des erreurs d'écriture.

A la lecture du rapport de debugage de k3b il semble que la version de cdrecord ne soit pas adaptée au kernel, mais est-il possible d'en trouver une autre (officielle) pour (k)ubuntu ?

Sinon :
- je n'ai pas essayé avec un live-cd car je n'ai qu'un seul lecteur/graveur de cd (qui marche)
- en mode simulation aucune erreur ne se produit
- Voici le rapport de debugage de k3b :
