Using K3B in KDE
Note: depending upon your distribution, K3B may or may not be included with the installation of KDE. If it does not appear in the KDE application launcher, you should be able to install it using your operating system's software management system. On a FreeBSD system, you can install the K3B package. If you are running an older version of KDE, use the pkg_add -r k3b command. If you are running KDE4, use the pkg_add -r k3b-kde4 command instead. On a PC-BSD system, you can install the K3b PBI using Software Manager.
To burn your ISO, launch K3B and click "Tools → Burn Image...". Figure 220.127.116.11a demonstrates this screen on a KDE4 system. On a KDE3 system, the menu item may appear as "Burn DVD ISO Image...".
A new window, seen in Figure 18.104.22.168b, will launch. Click the blue folder to browse to the location of your .iso file.
Once your file is listed, ensure a blank DVD is inserted and click the "Start" button. K3B will automatically eject the DVD once the burn is complete.
