I've just launched K3b for the first time after a fresh install of Kubuntu 8.04 and get the following message...

No CD/DVD writer found.
K3b did not find an optical writing device in your system. Thus, you will not be able to burn CDs or DVDs. However, you can still use other K3b features like audio track extraction or audio transcoding or ISO9660 image creation.

So, I can't burn CD's or DVD's at the moment (

Can anyone please explain what's wrong?

Many thanks.
