LiveCD hangs when removing boot CD for burning another

view story

http://askubuntu.com – I downloaded in image of 12.04 and I want to burn it onto a CD. Apparently each time I boot to the 10.10 LiveCD and try to burn the image using the default application (Brasero disc burner), when I replace the LiveCD with the empty CD, the system freezes. What do I need to do so the system doesn't freeze and lets me burn my image? (HowTos)
