[ubuntu] ISO master? (trying to create my own .iso)

view full story

http://ubuntuforums.org – Has anybody used this app much? I got it installed, and I can highlight the files that I want to add to an .iso, but when I hit the Code: add button in the middle of the GUI to try and add the files to create the actual .iso it doesn't do anything at all with the highlighted files..... So is there something that I am missing here? I might just end up giving up on it and doing it the old fashioned way in command line I guess.... Was just hoping for a quick and easy way to create my own .iso's Any help from some more experienced pros out there would be GREATLY appreciated... (Hardware)
