Just found the problem, which is quite mundane. udev creates automatically the device for the cdrom, in my case /dev/sr1, with ownership root:disk. The attributes are rw-rw----, which means as a normal user I can't write to it, K3B run as the normal user can't either. The test with dvdrecord was done as root and succeeded. When I changed /dev/sr1 to rw-rw-rw, it worked in K3B as well. Albert -------- Original Message -------- Finally can confirm that the dvdrecord command works. What I did wrong was NOT using a file with length zero to start with as the backend, so it was seen as a readonly CD/DVD, forgot that READMEs are there to read ;-) because it can be found in README.mmc K3B and nautilus (the Fedora desktop, rightclick "Open CD/DVD Creator) don't work. They both keep asking to insert a blank CD/DVD. As said the dvdrecord command works like a charm, so it is mostly working.
