DVD+RW and DVD-RAM media get treated as blank media regardless wether they

Options -audio and -multi are not allowed. Only one track is allowed.
-toc does not return information about the media content.
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second). Currently
there is no difference between -sao and -tao. If ever, then -tao will be the
