I can't seem to burn the boot disk

Can anyone help me? I use nero to burn the utopia bootdisk and I can't seem to have one burned properly. I tried several times with several different versions of the image for nero and I can't seem to burn it. Everytime I put a burnt disc in my DC, nothing happens and the audio cd play screen pops up with 00:06 secs as the length of my disc...can anyone help me?
