No that isn't going to work
livecd-iso-to-disk is only trained to work with fedora generated iso's
that buntu derivative uses a different squashed file system layout.

Ah the commandline always where something wonderful happens :-)
here's what I did:
mount the iso
cp all files & directories to your bootable stick/media
install grub or syslinux to stick/media:
note ubuntu uses grub by default so you should already find a usable
grub.conf, It can also be called menu.lst in /boot/grub
In my case I used syslinux and modified the config according to the original.
