Problem using a TEAC DV-W22E with dvd+rw-tools/cdrecord-prodvd/dvdrtools.

Hello,

I am using a TEAC DV-W22E R.0A on my notebook, which is a all in one
CD-R/RW and DVD-R/RW player and writer. My main OS is FreeBSD 5.2.1
(RELEASE-p4) and I already succeed in:

 - write CD-R (cdrecord);
 - write/rewrite CD-RW (cdrecord);
 - write a DVD-R (growisofs).

But it seems _not_possible_ to write (or rewrite or blank etc.) a DVD-RW.
Here is the exact version of software I try to use:
 # portversion -v | grep -i "dvd+rw-tools"
 dvd+rw-tools-5.19.4.9.7
 # cdrecord -version
 Cdrecord 2.00.3 (i386-unknown-freebsd5.2.1) Copyright (C) 1995-2002 Jörg

 # cdrecord-prodvd -version
 Cdrecord-ProDVD-Clone 2.01a24 (i386-unknown-freebsd5.2) Copyright (C)
 1995-2004 Jörg Schilling
 # dvdrtools -version
 [...]
 Based on:

I followed the steps from the documentation, especially those:
 - http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/
   creating-dvds.html
 - http://fy.chalmers.se/~appro/linux/DVD+RW/
 - ftp://ftp.berlios.de/pub/cdrecord/ProDVD/README
 - http://machiel.generaal.net/index.php?subject=dvdrtools

1/ For example, when I try to blank a DVD-RW in sequential mode, I get:
 # dvd+rw-format -blank=full /dev/cd0
 * DVD±RW format utility by <appro@fy.chalmers.se>, version 4.9.
 :-( failed to locate "Quick Format" descriptor.
 * 4.7GB DVD-RW media in Sequential mode detected.
 * blanking |:-[ READ TRACK INFORMATION failed with SK=3h/ASC=11h/ACQ=05h]:
 Input/output error

2/ When I try to put a DVD-RW in the restricted overwrite format, I get:
 # dvd+rw-format -force=full /dev/cd0
 * DVD±RW format utility by <appro@fy.chalmers.se>, version 4.9.
 * 4.7GB DVD-RW media in Sequential mode detected.
 * formatting .:-[ READ TRACK INFORMATION failed with SK=3h/ASC=11h/ACQ=05h]
 : Input/output error

Because the three software I try seems not working, I tend to think that
this particular writer is not (yet?) supported.
Is there something I can do in order to make it working?

Thanks in advance for your replies,
