[Cdrtools-support] Can't write dvd-rw disk with cdrecord

[Артур И. <art...@ya...>]

I can't write dvd-rw disk with cdrecord. dvd+rw-tools work perfectly
fine, but I don't want to use both tools to record cd/dvd when I can
only one. I'am using OpenBSD 5.8

First I blank dvd with:
$cdrecord -v -dev=/dev/rcd0c -blank=all
Using generic SCSI-3/mmc-2 DVD-R/DVD-RW/DVD-RAM driver (mmc_dvd).

Then I reload disk and writing with:

I suspect that problem with bad media/manufacturer, but dvd+rw-tools circumvent
this somehow.

Thank you!
