iLife '11 Installation Failed? Please Help!

Okay so basically I wiped my Mac and clean installed OSX Snow Leopard version 10.6.7, then after the installation completed I put the Application Install DVD in (installs the iLife programmes) and went through the necessary steps prior to install, when I actually click 'install' it says 'preparing to install' then within 1second a failed screen shows saying

The Installation Failed.

An Unknown installation error occurred.

The Installer encountered an error that caused the

installation to fail. Contact the software manufacturer

for assistance.

I've looked around the support forums doing all the suggested fixes, I have so far : deleted the Java folder from the System > Library folder,

verified the disk permissions then repaired them if any errors where found.

I also improvised and downloaded a torrent of iLife 11 (not to intendedly use but to test to see if there was a problem with the disk) and then when I ran it I got the exact same message!! So the problem is not with the actual iLife / Bundled Software disk!!

Please help as I really require the programmes such as iMovie and Garageband for what I do...all help is welcomed and will be praised and below you can find a picture of the error screen! Thank you!!
