When i try to burn a dvd in linux with k3b i get the following everytime.
I once tried to burn a dvd-rw and it worked... the i burned a dvd and it worked.. after that i tried again and it failed. In Windows my dvd's burn fine... slow but fine.. my only guess is to get a new burner... or is gowisofs the problem?
