And for even more info,

read the doc in /usr/src/linux/Documentation/cdrom/packet-writing.txt

I followed your advices and these are my results:

created the right block devices into /dev/pktcdvd:


Yoy should not have to do that.  Take a look at /etc/init.d/udftools,
it sets up the devices.  The /etc/init.d/udftools I "had" been running
was not working correctly so I modified it like:

/etc/init.d/udftools (Modified)
--snip--
PATH=/sbin:/bin:/usr/sbin:/usr/bin
DESC="udftools packet writing"
PKTSETUP=/usr/bin/pktsetup
DEFAULTFILE=/etc/default/udftools
DEVICES=""
#  Added next line
NEWINTNAMES="dvd cdrw"   # Added this
#NEWINTNAMES="0 1 2 3" UDEVNAMES="/dev/pktcdvd/0 /dev/pktcdvd/1 /dev/pktcdvd/2 /dev/pktcdvd/3" 
UDEV=""
NEWINT=""

if test -e /dev/.devfsd; then
   OLDINTNAMES="/dev/pktcdvd/0 /dev/pktcdvd/1 /dev/pktcdvd/2 /dev/pktcdvd/3"
else
#    OLDINTNAMES="/dev/pktcdvd0 /dev/pktcdvd1 /dev/pktcdvd2 /dev/pktcdvd3"
# added next line
    NEWINTNAMES="/dev/pktcdvd/dvd /dev/pktcdvd/cdrw"  # Added this
fi
--snip--

Now when /etc/init.d/udftools start is run it creates the files
/dev/pktcdvd/dvd and /dev/pktcdvd/cdrw, and deletes them when /etc/init.d/udftools stop is run. 
# ls -l /dev/pktcdvd
totale 0
crw-r--r--  1 root root  10, 61 18 feb 19:38 control
brw-r--r--  1 root root 254,  0 18 feb 19:29 pktcdvd0
brw-r--r--  1 root root  97,  0 18 feb 19:29 pktcdvd1
I created pktcdvd0 and pktcdvd1 rispectively with major 254 and 97 just to make some tests.
/etc/init.d/udftools should do all of this 
# pktsetup /dev/pktcdvd/pktcdvd0 /dev/hdb
ioctl: No such device

If you have setup the /etc/default/udftools file correctly, and then
pktsetup is then done by the /etc/init.d/udftools file.

My /etc/default/udftools file:

# Drives to register for packet writing:
DEVICES="/dev/hdc /dev/hdd"
NEWINT=true
NEWINTNAMES="dvd cdrw"



I use pktsetup from the latest CVS of udftools so I think to be up to date.


Try the above setup and let me know id it works for you.  Note I have a DVD and
CDRW drives so I defined them both. You should modify the scripts if you have only the DVD RW drive.
udftools 1.0.0b3-9. UDF not compiled into kernel not modules. I am not running udev.
Ok, I found that the problem is caused by pktsetup which I compiled from the cvs sources. Perheaps the cvs sources are not so up to date with the new pktcdvd kernel module, so I downloaded and installed udftools-1.0.0b3-9 
i386 deb package and everything turned bright.
Being a Fedora user and not wanting to mess with the debian scripts included in the package I added these lines to my /etc/modprobe.conf: 

# PACKET WRITING:
alias /dev/pktcdvd/0 pktcdvd
alias block-major-252 pktcdvd
install udf     /sbin/modprobe --ignore-install udf; \
               /usr/local/bin/pktsetup 0 /dev/dvd
In this way everytime /dev/pktcdvd/0 is mounted I get my dvd device correctly mapped to pktcdvd. It could sound as a sort of kludge but it works. 
Thanks to everyone who put me to the right direction to solve the problem!
