I did a find for grub.conf and there are two copies of this file on the 
system, one in /etc and one in /boot/grub however the file in /etc is 
just a link back to /boot/grub/grub.conf

To check that this is the file being used I commented out the second 
title which then did not appear on the grub screen so I am sure that I 
am editing the correct file.
