Evtl. deswegen (aus /usr/share/doc/dvd+rw-tools/index.html):

In order to optimize seek times DVD[-ROM] players calibrate their
mechanics every time the media is loaded by sliding the optical head
some place, picking up the signal and noting the physical block
address underneath the lens. In order for this procedure to work with
re-writable/recordable media, that particular spot has to be written
to [or de-iced in DVD+RW case]. Some units slide the head to 30mm
[radial] to calibrate, some to 35mm. In order to keep such players
"happy," make sure that at least 1GB is written [before you attempt to
mount it in DVD-ROM unit].
