dvdisaster is specialized in working with error correction data and reading
of defective media. Creating ISO or UDF images and writing them to a medium
is a totally different business, and also bears high complexity.
We do not want to re-invent medium writing in dvdisaster. Instead we
continue using the CD/DVD/BD writing software which you have got when
purchasing your drive.<p>

This may take a while depending on the image size and the
available free space on the medium. Processing a DVD image with about
20-30% free space should take about 5-10 minutes on recent hardware.

Select the "DAO" ("disk at once") writing mode if supported by your drive.
This improves the compatibility between the medium and the error correction.
In addition this prevents you from accidentally adding more sessions
to the disc which would destroy the error correction data.
