Maybe it come from the way I try to burn :

#!/bin/bash
if [ -z "$2" ]; then
	echo "usage : $0 DVD_title DVD_dir [write speed]"
	echo "That will write a DVD with video structure if there a VIDEO_TS."
	echo "And without video structure if without VIDEO_TS dir"
	exit
fi

UDF=`find $2 -size +2G|wc -w`

unlock() {
	cdrdao unlock --device 2,0,0 --driver generic-mmc && sleep 1
}

sync

ulimit -l unlimited

if [ $UDF -eq 0 ]; then
	COM="-f -J -r -graft-points "

	if [ -z "$3" ]; then
		COMCD="-v dev=2,0,0 -dao fs=1000m "
	else
		COMCD="-speed=$3 -v dev=2,0,0 -dao fs=1000m "
	fi
	VIDEO=`ls $2|grep -i VIDEO_TS 2> /dev/null   |wc -w`
	if [ $VIDEO -eq 0 ]; then
		OPTS=$COM
		SIZE=`mkisofs -f -J -r -graft-points -quiet -print-size -V $1 $2`
	else
		OPTS="$COM -dvd-video"
		SIZE=`mkisofs -f -J -r -graft-points -quiet -print-size -dvd-video  -V $1 $2`
	fi
	mkisofs $OPTS -V $1 $2|cdrecord $COMCD tsize="$SIZE"s -
else
	COM="-iso-level 3 -udf -f -J -r -graft-points "

	if [ -z "$3" ]; then
		COMCD="-v dev=2,0,0 -dao fs=1000m "
	else
		COMCD="-speed=$3 -v dev=2,0,0 -dao fs=1000m "
	fi
	VIDEO=`ls $2|grep -i VIDEO_TS 2> /dev/null   |wc -w`

#unlock
eject /dev/sr0
eject -t /dev/sr0
sleep 8
mount /mnt/cdrom
ls -alh /mnt/cdrom
DF
umount /mnt/cdrom
sleep 1
eject /dev/sr0

It's the first time I try to use DL disks... any idea on what i shall do ?
