OK, so I burnt an image using DvD Decrypter.
I have another PC with a DvD reader, stuck it in, and... It works!!
Took the disc downstaires to my DvD player, to see if it would work on the big system. I put the disc in, and my DvD play just kept saying 'loading loading loading' and eventually stopped.
My DvD machine is about 2 - 3 years old, region free, I would of thought that meant it WOULD read - discs??? Is there something I'm missing here???
Cheers for the advise so far, I'm getting there!! ..ish!!
