To force your system to accept downgrading genisoimage, you should:
#Download genisoimage deb package for gutsy [http://packages.ubuntu.com/gutsy/genisoimage here] onto your harddisk
#Use dpkg using the command line in a terminal
Go into the directory where you have downloaded the deb file and type
sudo dpkg --force-downgrade -i genisoimage_1.1.6-1ubuntu3_i386.deb
The system will ask for your password, and that's all !

Then "Lock this version" or it will want to upgrade.
