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.

/etc/init.d/udftools should do all of this

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"

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.

Don't know about that being a problem.  (??)

I am not running udev.
