Every time I want to burn media, I have to look up again what the syntax is. So, for future reference, this post.

CD ISO image: 

wodim dev=/dev/sr1 -eject  ubuntu-10.04-server-amd64.iso

For DVD’s it’s different. If you mimick the above command, you will have a DVD with the ISO file on it. I don’t know exactly, but you have to specify /dev/dvd=image.iso or something. When the next time I burn a DVD ISO arrives, I’ll update this post.
