Did you format the dvd;
sbin/mke2fs -b 2048 /dev/scd0
then you can use the dd command;

Looks like I was wrong, see if this helps;
growisofs is the main command used for writing the DVDs. To write DVDs, use this command:

#growisofs -Z /dev/cdrom -R -J /folder_to_copy

To copy an image file instead, give this command and it will writeyour DVD.

#growisofs -Z /dev/cdrom=image.iso

What happens when you try it like this;
#growisofs -Z /dev/scd0 -R -J /home/arpan/Desktop/backup
Also if there is only individual files you want to copy you may be able to create a tar.gz and save it that way;

Are you sure you have /dev/scd0 in your /etc/fstab ?
What happens when you do cdrecord --scanbus
