The CD/DVD preferences are used to control how CD's or DVD's are created using FotoAlbum. Generally these are settings that only need to be defined once for a given system. Due to the variations in how CD/DVD burners behave, there is not a single solution that works for all drives. If you have problems with burning directly to a CD or DVD, you might try the other settings.
Use Nero: If you have Nero version 6 or later installed on your system, then this option will be available. This generally works the best and should be used if it is available to you.
Use CD/DVD Writer Pro: This option uses a CD/DVD library that is installed as part of FotoAlbum. It is generally the best option to use if you do not have Nero 6.
Use Binary Magics: This is a third option for burning CD/DVD's. This works well for certain CD and/or DVD drives.
