yeah using disk utility is really easy, I use it for linux cds a lot. first make sure the iso file is located in disk utility, it should show up in the white space on the left side of the window, if not drag the file from the desktop(or wherever you have it) onto the white space. After you do that, highlight the iso and click "burn" (its at the top of the screen). The only suggestion I have is using a low burn rate so that the data is transfered more accurately.
