DVD Burning

[Eric van Gyzen]

I have:

 - FreeBSD 5.1-RELEASE
 - HP DVD Writer 300i (ATAPI, using ATAPICAM)
 - Imation DVD-R media

I'm trying:

  # growisofs -speed=1 -Z /dev/cd0=/tmp/foo.iso
  :-[ Unit won't start: 40901 ]
  :-( /dev/cd0: unsupported MMC profile 10

  # dvd+rw-mediainfo /dev/cd0 
  INQUIRY:                [HP      ][DVD Writer 300c ][7H29]
  GET [CURRENT] CONFIGURATION:
   Mounted Media:         10h, DVD-ROM
  READ DVD STRUCTURE[#0h]:
   Media Book Type:       01h, DVD-ROM book [revision 1]
   Legacy lead-out at:    0*2KB=0
  - [unable to READ DISC INFORMATION(33001)]: Invalid argument

Does the second command really think the media is a read-only DVD-ROM?

I have also tried dvdrtools.  I can send the output if it might help.

Thanks in advance!
