FC12 livecd-iso-to-disk woes

[T. Horsnell]

Hi all,
I'm trying to make a USB version of the FC12 livecd.
I follow the instructions at:

http://fedoraproject.org/wiki/FedoraLiveCD/USBHowTo

and type (as root):

# livecd-iso-to-disk --format --reset-mbr Fedora-12-i686-Live.iso /dev/sdc1

but the resulting USB stick just gives me 'Boot Error' when I boot it.

If I use the dd method:

# dd if=Fedora-12-i686-Live.iso of=/dev/sdc bs=8M

it boots correctly. I ultimately want a persistent-storage
area so the dd solution is no good for me.

Any ideas?

Cheers,
Terry
