Actually if you don't care about the GUI and compatibility with other
systems, you can do DVD burning with growisofs only (without
mkisofs/genisoimage respectively from cdrtools or cdrkit).

AFAIK this might cause problems if you use auto-mounting software and
forget to disable it before writing.

The good part is that you don't need isofs for DVDs. Actually
you don't need any fs at all. You could write files like this:

growisofs -Z /dev/dvd=Test-_2008.07.04-10.06.53_1.tar

Unfortunately I have I/O errors (ruined media) often with this method,
so I use:

tar cp path/to/files | \
pipebench -q -b 50000000 | \
growisofs -Z /dev/sr0=/dev/fd/0

"pipebench" is in portage and provides two important advantages:
- you can check the speed and make adjustments it if necessary
- you can adjust the buffer (-b)


To restore the files from the above backup:

tar xpf /dev/dvd

It works perfectly for me.

You can burn this way images with your preferred FS.
