Hi Folks,
   I'm having bad problems with a dvd-burner using
NetBSD-3.0 (GENERIC.MPACPI) on i386 and the cdrtools-ossdvd-2.01.1.35
pkg from pkgsrc-2005Q4.
   Running the command...
      cdrecord -v dev=15,0,0 driveropts=burnfree MyDVD.iso
starts the burn process and gets some of the way through, then dies
badly. Console also reporting messages. Outputs below. Happy to test
code on this machine. If anyone wants more info, just ask.

Console....
