Hi All,
Sorry it's been a while the reason is I have been trying to obtain / borrow a benq 1620 dvd writer just to see it that made any difference.
I have tried the swap trick and yes the copy worked

, so in my novice opinion that means the ISO I have created works, so a real step in the right direction.
I can try writing the disk at a slower speed but I really don't want to waist another disk if it is possibly down to the LG writer I am currently using.
Anyway that's all for now folks and I must say I am really appreciative of all the help you have already given, as it has given me a way forward.
