I know this is really not an answer (about mounting "blank" CD/DVD). I
burn DVDs with a single command growisofs which comes with dvd+rw-tools,
say I want to burn all in current directory to DVD:

growisofs -dvd-compat -Z /dev/cd0 -dvd-video -V DVD .

(skip some options if you need just data DVD not DVD to be played on stand
alone DVD player).

When I need to burn from iso disk image (either CD or DVD) I use cdrecord
command which comes with cdrtools package:

cdrecord -dao disk-image.iso

When I need to create Bluray disk (playable on stand-alone BD player), my
path is longer: I first create disk image in a file (of necessary size),
format it (make filesystem), mount it, copy there all necessary, unmount,
then burn the image. Something like this:

touch dvd.img
du -sk BDMV
# in the above I just found out how much space I will use on DB
# and use the result in the following command - get it slightly larger...
dd if=/dev/zero of=dvd.img bs=1024 count=10000000
mkudffs --vid AVCHD dvd.img
mkdir tmp
mount -o loop dvd.img tmp
rmdir tmp/lost+found
cp -R BDMV CERTIFICATE tmp
umount tmp
rmdir tmp
growisofs -Z /dev/dvd=dvd.img


I hope, this helps.
