Just bought an external DVD RW drive and tried to do backups of my Netbook onto DVDs.
In LXDE I tried Xfburn, but this seems to be restricted to CDs and doesn't do DVDs. Grafburn does recognise DVDs, but gave some trouble, but I couldn't see how to make it go down symbolic links, so that was no good. Can't see any other burners in the LXDE repo by searching "burn" or "burner".
Switched to a partly installed Minime, and installed the latest K3B. AOK, handled symlinks perfectly. But, unlike the earlier version of K3B I use on another computer the disks were closed and not appendable. I tried to find the settings to create an appendable disk (CD or DVD) but couldn't find them.
