This is certainly not DFSG-free: requiring me to provide complete support
for a release in order to distribute modified versions isn't free at all.
(It's GPL-incompatible, too, but although the cdrecord and dvdrtools
source packages contain several GPL components, none of them appear to
actually be linked to the problematic code.)

I don't know if requiring me to include my email address is DFSG-free.

I don't know if these terms are free to the FSF--note that dvdrtools uses
GNU Savannah.

Requiring that I display a copyright notice and license blurb is OK, but
requiring that I not modify the code that does so is not.  This even
prevents me from fixing the output: "cdrecord -version" displays garbage
ISO-8859-1 on my UTF-8 terminal.
