nautilus cd-record

[Mark Grieveson <dg135@torfree.net>]

Hello.  Nautilus cd/dvd creator no longer writes to CDs or DVDs on my 
system.  It only gives the choice of "file image".  Also, applications 
such as k3b, gnomebaker, and XcdRoast, do not write bootable cds, but 
only data.  For instance, when I try to write the latest Ubuntu, or 
Libranet, install disks, they do not boot.  I used to be able to write 
bootable CDs.  Anyone with any ideas about this, please share.  Thanks.
