Worked finally.... Seems the burner in my home PC was the problem.

At work I have a Dell PC which burnt the image using Alcohol 120% no problems.

At home I have a HP writer 400c which won't use Alcohol 120% to burn the image, hence I made a few coasters!! Good thing too... I need them the put my beer on.

I think the lesson learnt is, if you can browse the contents of the CD after you have imaged it then it is OK. In my case after it burnt the image(home PC) the CD appeared to be empty but, clearly you could see it had been written to.

The update worked a treat.
