<p>These are just guesses</p>
<p>Have you ever successfully written a DVD on your installed system? How about a bootable .iso? (It sounds like you're trying to write an .iso and get a bootable dvd.)</p>
<ul>
<li>Could it be the way you're using brasero?</li>
</ul>
<p>A possibility is the way you're using brasero (which I've only used once.) Are you trying to use it to write an .iso image? If so, that's different from writing the .iso image into an iso file system as data. (I.e. If you're using the "data project" option, the file system itself takes space, so there may not be enough room for the .iso file and in any case it would only show up as a data file. You'd have to use the "burn image" option to do a raw copy and get a bootable DVD.</p>
<ul>
<li>Could it be a permissions problem?</li>
</ul>
<p>The Fedora install should have gotten this right, but sometimes there's a glitch. You may be a victim of Murphy.</p>
<p>Type ls -l /dev/dvd. That should be a symbolic link to your actual device (say /dev/sr0).</p>
<p>Then type ls -l /dev/sr0. Look at the permissions and groups. Chances are that /dev/sr0 is owned by root and group cdrom. Chances are also that the permissions for sr0 are "brw-rw----"</p>
<p>Then become yourself again and type "groups". Chances are that you are NOT a member of cdrom. If so, you do not have permission to access the device directly for write.</p>
<p>Now do a "ls -l" on the program you're using to try to write to the device (brasero). If IT also doesn't have proper permissions, you'll never get it to write.</p>
<ul>
<li>Personally, I've found K3b to be easier and more reliable to use than brasero. I once tried to burn an iso image using brasero and ended up with a coaster. Using K3b I've never had a failure.</li>
</ul>
<p>Good Luck.</p>
