Inappropriate ioctl for device

Hi,
I'm trying to do some packet writing with my PIONEER DVR-106D dvd-rw but 
I'm running in the problem that it doesn't seem to be recognized by the 
kernel module (at least this is what I think).

This is my system:
kernel 2.6.10, pktcdvd 0.2.0a, udftools 1.0.0b2, dvd+rw-tools 5.21.4.10.8-2

This is the output from dvd+rw-mediainfo:

Formatting and blanking the media goes without any problem but if it try 
to issue pktsetup:

[root@artemide ~]# pktsetup /dev/pktcdvd /dev/dvd
ioctl: Inappropriate ioctl for device

The kernel module is loaded succesfully so don't know why I get this error.
Could be my DVD burner blacklisted or inappropriate for packet writing? 
Or am I missing something?

ciao,
