I hate to slam burncd because it does the job, but I've always found
cdrecord / mkisofs to be a better set of software for burning CDs than
burncd.. Besides, burncd chokes on permission errors on my machine
whereas cdrecord keeps on humming away with issue, and I've been using
it for 2 releases now (6.1, 6.2).
