Have you tried mounting it as a vnode ? and mounting it R/W ?
mdconfig -a -t vnode -f file.img
mount -t <type> /dev/md0 /mnt/rw_dvd
Where <type> may be cd9660 or some other format of the image.
I haven't seen reported success with this method (checked with various google
searches), but perhaps there's something along these lines *will* work.
Hope that helps,
