Tried this yet ?
        dd if=/dev/cd0 bs=32k of=/tmp/bla count=50
        file /tmp/bla
Try in other BSD or Linux/ Solaris ( even MS-Ugh!) just to know if
other OS say its OK ?  For any IX you could even mail or ftp 1st
chunk to others to look at.

man fsck        # fsck -n -t            ls -li /*bin/fsck*

Think what sort of DVD you told MAC to create.  Man cdrecord
give insight on MAC formats, (albeit CD size, not DVD) cdrecord
comes on FreeBSD come from /usr/ports/sysutils/cdrtools sorry dont
know where on NetBSD, but source here ftp://ftp.berlios.de/pub/cdrecord/

When you burnt the media did you close the media session ?

Man extracts 
burncd      -m            close disk in multisession mode (otherwise
                disk is closed as singlesession).
                (OK thats from Man FreeBSD-7.1 but maybe in netBSD too)

Common packages:

cdrecord   -multi Allow  multi  session  CDs  to  be  made.  
                This flag needs to be
              present on all sessions of a multi session disk, except you want
              to  create a session that will be the last session on the media.

mkisofs   -C last_sess_start,next_sess_start
              This option is needed when mkisofs is used to create  a  CDextra
              or the image of a second session or a higher level session for a
              multi session disk. 

Cheers,
Julian
