- burning CD's is no problem;
- When I put a data-DVD in the drive I cannot read the contents in Konqueror;
- When I open K3B it gives a message that problems may occur by the settings in fstab (automounting?);
- after mounting the device in a terminal (mount /media/dvdrecorder), I can read the contents of the DVD!
- burning a DVD at first seems to be running oke; but after the weldone :-( message and looking at the contents it is wrong. But at the dvd you can see that the surface is changed.

The questions:
- is the configuration in fstab, mtab and auto.misc correct?
- does anyone has suggestions?
I hope that someone can help me.
greetings Ed
