Burning mixed permission files to disk problem?

Hi; I started out to do something I though should be fairly easy but I have been at it all evening. I am trying to burn some data files to DVD as a backup. Here is the problem as far as I can tell. Brasero from root won't burn the files directly but wants to turn them into an .iso. Details: I have a backup partition on which I keep my personal backups as well as files and directories owned by root such as /etc. I was getting ready to upgrade to Fedora 14. I decided that there was only some of my backup files I wanted to further back up to a DVD disk. The total size fits on one disk. Brasero will back up personal files but won't back up root's files. If I su or sudo brasero and try it from there, brasero wants to create /root/brasero.iso. Same happens with the other command line burny-thingy-automatic program that goes with Nautilus. (I can never remember it's name). The manual is silent on why root and user files won't mix or on how to burn root files. Plus several annoying things happen with unwanted programs popping up when using brasero and inserting discs. -- Regards Bill Fedora 13, Gnome 2.30.2 Evo.2.20.2, Emacs 23.2.1
