The Media Type setting *should* be totally irrelevant (i.e. can be anything
you want).

Well, that is nice to hear :-)
Turning off spooling certainly helped. I've now modified the code to ignore
normal data spooling for DVD devices. The device type is not important for
Linux systems (I think you mentioned your OS, but I forgot), but for some
OSes such as FreeBSD (if I am not mistaken) having Device Type = DVD is
critical -- otherwise it thinks it is working on a File. Judging from the
output you have posted, I would guess that you are running a Linux system and
so this Device Type was not a factor.

Yes, if you figure that one out, please let us know.
