I went out today, and paid way too much for a few DVD+RW's for testing. Unfortunately I ran
intot a problem.

So I wnet and read the sugested README:


Notes about DVD-Recording:
==========================

cdrecord does not support DVD recording. If you need it you have the
following options:

* cdrecord-ProDVD: Joerg Schilling is also author of cdrecord-ProDVD. This
  software is free for personal use but not free software according to the
  DFSG and therefore not part of Debian GNU/Linux.

* dvdrecord: A fork of cdrecord 1.11a15 with DVD support. As far as we
  know it it is not actively maintained.

* Apply the dvdrecord-patch to cdrecord and compile it yourself:
    apt-get source cdrtools
    cd cdrtools-<version>
    fakeroot debian/rules dvd=yes cdrecord

    Be aware that we will probably ignore bugreports for cdrecord+dvdpatch
    unless they can be reproduced without the patch.

-------------------

Why is this patch not applied by default?

* We are not the upstream authors of cdrecord and cannot fix most of the bugs
  ourselves, but will forward them to upstream. The author of cdrtools is
  not interested in maintaining a forked version of his software.
  
* We aren't interested in and cannot play upstream (aka main software author)
  for the dvd-patch.

* There is no active upstream for the dvdrecord-patch either. 

* It may break cdrecord. And as far as we know its only tested on Pioneer
  A03 DVD Writer. So there is no guarantee that cdrecord still does its
  work as it should nor that this patch really works for most of the
  DVD Writers.

I suppose I could try building this with teh patch, but the wording of this 
README does not do a lot to make me expect it work on my hardware.

Is there an alternate tool I can use? I'm on a machine built from KnoppMYTH, 
which of course is Debian derived.

What are my options here?

And thanks for all the help on this!
