burning .nrg files

[bruco2]

Hey guys. I have the following problem. I have three image files (.nrg) from the game diablo2. I know I have to burn them with Nero. But what I don't know is how to give the right labels to the three CD's. If I burn an image file, the CD gets automatically the label "New". I have to give the follwing names to the CD's: "install" ,"play" and "cinematics". How do I do that? Thanks.
