Hi,
for completeness: One of the two Debian patches replaces
the theory of SAO-versus-TAO.
It turned out that the function, which transmits the

of blocks.)

As source I used the downloaded ISO of PartedMagic from 2012_11_30.

To my own experience, the code which governs creation and burning of

i noticed that the properties of DVD-RW are misrepresented

DVD-RW can assume two states: sequential and overwritable.

of one or more burn

i propose to fix a bug in the libburn plugin of Brasero

You experience problems between drive and medium after
Brasero, libburn, and the drive all accepted the medium

third one.
This narrows the set to: DVD-R, DVD-RW, DVD+R, DVD+RW.

You should try a different brand of media. Best a different

If all reachable kinds of DVD fail, then consider to exchange

the first message about lack of permissions is common and should be

If in doubt whether the power is really off, press the drive's eject
