First, do mount and make sure that the media has not been mounted. If
so, unmount it. That *might* be the root cause.

Do you have an /etc/cdrecord.conf? Might have some things like

    CDR_DEVICE=2,0,0
    cdrom=          /dev/hdc        -1      -1      burnfree

On 4.x, this last line seems to be the item used for specifying the
device. This 4.x has only a CD-RW, not DVD. My 5.x show DVD capability
too because I have a DVD burner on that one. An ls -l of /dev/d* should
show some symbolic links of hd*. This on my 5.x.

    cdrecord -dev=cdrom -prcap

    Device type    : Removable CD-ROM
Version        : 0
Response Format: 1
Vendor_info    : 'CDWRITER'
Identifikation : 'IDE5224         '
Revision       : '0012'
Device seems to be: Generic mmc CD-RW.

Drive capabilities, per MMC-2 page 2A:

  Does read CD-R media
  Does write CD-R media
  Does read CD-RW media
  Does write CD-RW media
  Does not read DVD-ROM media
  Does not read DVD-R media
  Does not write DVD-R media
  Does not read DVD-RAM media
  Does not write DVD-RAM media
  Does support test writing


Compare the cdrecord.conf against what this shows. It will not include
devices like cdrom here. That is a symbolic link to /dev/hdc (in my
case).


    # cdrecord -scanbus

For me, ... 

    scsidev: 'ATA'
    devname: 'ATA'
    scsibus: -2 target: -2 lun: -2
    ...
    scsibus1:
        1,0,0   100) 'CDWRITER' 'IDE5224     ' '0012' Removable CD-ROM
        1,1,0   101) *
        1,2,0   102) *
        1,3,0   103) *
        1,4,0   104) *
        1,5,0   105) *
        1,6,0   106) *
        1,7,0   107) *

Do you have an env variable (from bash prompt)

    echo $CDR_DEVICE

I'll go over to my 5.X and re-write a 5.1 DVD now.

More after you reply.
