OK, so I followed the steps listed by Tyler (cheers for your help mate

)
Created the *.iso file using IML2ISO.
Trying to burn iso to DVD-R. Nero doesn't want to have any of it - 5.5.9.0 - using File > Burn Image - saying compilation will not fit onto blank CD - even though I am choosing to burn as DVD-Image
Anybody here got any suggestions or other ways to burn iso image to DVD-R ?
