problem writing iso image with dvdrecord

[Nataraj]

I have ubuntu 10.04.2 (all current updates applied) running on a MAC
mini with a plextor dvd writer and I am unable to write a dvd iso image
with dvdrecord. I am able to boot a vmware virtual machine running
fedora 14 (on top of that same ubuntu 10.04.2 mac mini) and connect the
dvd burner to the virtual machine and sucessfully write the same iso
image with dvdrecord on the same drive. I'm pretty sure this worked
under ubuntu a few months ago and suspect that something broke with one
of the updates. Any ideas?

The error that I get under Ubuntu is as follows:

dvdrecord -dao -data -overburn speed=4 dev=/dev/sr0 disk03.iso
