When you've finished designing your CD in one of the five projects, you need to click on the Write CD button to actually write the CD. When you've clicked on this button you'll be presented with the following dialog:
This dialog contains the finishing settings about your CD writer. The top list box, titled Preferred burn speed is where you can select your burn speed. If you select a speed higher than you actually have, you CD-Writer's maximum is used. The next list box, titled Preferred Fixating Setting determines if and how the CD will be closed. There are three options.
Neither the session nor the CD will be closed. This means that you can't use the CD, but you can add tracks to the session later.
The session will be closed. This means that you can use the CD on your PC. If you want to use this CD on a CD player, you must close the CD though. The advantage is that you can add another session any time you want.
The CD will be closed. You can't add any tracks to the CD anymore. The good thing about this is that the CD can be used in Audio CD players.
If you check the checkbox titled Eject after write, the CD will be ejected as soon as its finished burning. When you click select Simulation Mode, the burning process will be emulated, but nothing will be written on the CD. You can use this mode to test if everything is set up properly. The last option labeled On the fly burning will skip making temporary iso files of your project. This will save on diskspace, but it is more difficult to buffer. Only try this when you aren't using your computer heavily.
When you are finished, you can finally click on the Write CD! button, sit back and enjoy your freshly made CD.
