Ah well, I understand now.
But, I imagine that having some standard Python wrapper (or binding)
around cdrecord or whatever other tool used would be ideal, right?
I searched about this on Google and found out that using libburn would
probably be a good idea. It seems that pyburn is exactly what would be
needed: http://forums.belution.com/en/python/000/001/77.shtml
Sadly, it is not downloadable from there.

I found another backup tool written in Python for backuping on DVD:
http://www.linuxbox.com/tiki/tiki-index.php?page=python-dvd-backup
Maybe its code could be of any use?
It seems to be using dvd+rw-tools.
