Fair enough.  I don't know how to make burncd burn DVD-R's.  People 
have been able to use the port I mentioned to burn DVD-R's, at least if 
their hardware is capable of doing so.

The code is also GPLed. I'm looking, if at all possible, for an 
all-BSD
solution.
Is the license actually a genuine concern, or are you inventing 
excuses?
The license is a very great concern, for reasons I've mentioned
elsewhere.  We like to be able to look at and tweak the software we
use, and we can't look at GPLed code for legal reasons.
Well, you've done me the courtesy of answering my question.

I do not see why the GPL would prevent you from looking at or modifying 
DVD+RW-tools if you wanted to-- unless you plan on selling or 
redistributing closed-source DVD-burning software (seems unlikely)-- 
but it doesn't matter whether I understand these "legal reasons" or 
not.

Also, no BSD-based operating system should be dependent upon GPLed 
code. I'm glad to see that Jeroen and others are working on 
alternative toolchain components.
My opinion is that FreeBSD is better off having tools like "less" as 
part of the OS.  Come to think of it, "less" is now dual-licensed under 
both a BSD-style license and the GPL.  Perhaps you could ask Andy 
whether he would be willing to make dvd+rw-tools available for your use 
under a different license?

These discs won't just be for archival purposes.

I agree (for whatever that is worth :-)

Well I tried it and it does work with DVD-RW :-)  And while the 
documentation could use some improvement it does state you can
use DVD-R.

I use the "shim" with no problems at all.

Well that all depends on your philosophy regarding tools.

An excellent suggestion.  I'm paranoid when doing my backups.  After I
do them I do a restore -N.  If you want to be really check things do
an actual restore to a different location and do md5sum's to compare
the files.

I've taken a look at this port. Unfortunately, it's REALLY hard to
figure out the documentation (which consists of a few Web pages written
in very contorted -- almost unreadable -- English).
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.

From what I can tell, though, this software is really meant to work
with DVD+R, which records a little more than half as fast as DVD-R.
I need the speed, and so need to make sure it really works with DVD-R.
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...

Also, it looks as if this port runs on top of another utility called
"cdrecord", which itself runs on top of an ATAPI-to-SCSI shim.
dvd+rw-tools depends on mkisofs (aka sysutils/cdrtools).
For ATAPI burner devices, it will use ATAPI/CAM.
I'm worried that this ziggurat of utilities will not be anywhere near
as reliable as a simple utility that goes directly to the ATAPI drive.
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.

The code is also GPLed. I'm looking, if at all possible, for an all-BSD
solution.
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!

Does such exist? The man page for FreeBSD's "burncd" command hints that
it can can write DVDs, but doesn't say how.

Yes, FreeBSD can burn DVD-R's.  Please see 
/usr/ports/sysutils/dvd+rw-tools.  This port should work fine with an 
ATAPI burner such as your unit, but you may need to rebuild the kernel 
with:

device  atapicam

The command used is called "growisofs" and invokes "mkisofs" as needed 
as a dependency.  The manpage includes the following examples:

"  To  master and burn an ISO9660 volume with Joliet and Rock-Ridge 
exten-
   sions on a DVD:

growisofs -Z /dev/dvd -R -J /some/files

   To append more data to same DVD:

growisofs -M /dev/dvd -R -J /more/files

   Make sure to use the same options for both inital burning and 
following
   sessions.  To use growisofs to write a pre-mastered ISO-image to 
a DVD:

growisofs -dvd-compat -Z /dev/dvd=image.iso

   where  image.iso represents an arbitrary object in the 
filesystem, such
   as file, named pipe or device entry. Nothing is growing here  
and  com-
   mand name is not intuitive in this context."
