The man page for growisofs is the primary documentation; it's not a 
gem, but neither does it strike me as being far less understandable 
than "man burncd", "man mkisofs", or other documentation related to 
this topic.

Meaning what?  You want to make sure the software really works with 
DVD-R, but you are not willing to test the software yourself?  Hmm...

dvd+rw-tools depends on mkisofs (aka sysutils/cdrtools).
For ATAPI burner devices, it will use ATAPI/CAM.

Your concern could be resolved by verifying the data after you burn it 
to DVD, which, come to think of it, is a really fine idea when using 
any type of backup or archival mechanism.

Is the license actually a genuine concern, or are you inventing 
excuses?  Sigh.  FreeBSD contains lots of GPL'ed code: see /usr/src/gnu 
and /usr/src/contrib!


PS: You're welcome to use whatever software you want, of course, but 
the problem  you want to solve and issues you raised aren't 
particularly congruent.
