Nero - k3b == BlueRay.

I haven't blueray. And to me it is not necessary Nero

Nero 3 needs a new CD key.

Best burning software for Windows now on Linux! Iv been using it for almost 2 years now on Linux and been the best burning software Iv used for Linux. K3B just can't cut it compared to Nero. If you have a Windows CD-Key for Nero, you can use it for the Linux version :)
