See the wikipedia entry:
http://en.wikipedia.org/wiki/Universal_Disk_Format

"It [UDF] is an implementation of the ISO/IEC 13346 standard (also known as
ECMA-167), and an extension of ISO 9660."

And (somewhat paraphrased):

"A variable-length 'packet-written' CD-R(W) can be closed to a ISO9660
format by writing just by writing a table of contents on the CD."

I beg to differ. Growisofs is a front-end for mkisofs, combined with a
DVD recording program. See the growisofs manual page.
