Hello
I used the woody debian packet from the k3b website. There was a problem installing the package as it will write into folders already used bz another package. (I tries the kpackage programm first). After that I used apt together with a force option to overwrite existing folders (they have been empty anzway). (look with help for the synthax, cant remember it). This installed the latrest k3b and i was able to burn dvds. I used a pioneer burner and had no Problems using verbatim dvds. I´m still lockinh for cheaper dvds working with my burner.
Good luck
Simon
