Just to let you guys know (and for anyone else who might run into the same problem) I found the answer.

Out of intrest I sent this thread to my good man Mark Pascoe at Escape Studios, London who quickly spoted it.

I had UV mapped on an animated character and that was causing the problem. So what I did was to copy the geometry in question, move it out of the way and delete the history on the copyed geometry.

Then I went to Polygons --> Transfer Option Box and selecte UV Sets only then clicked Apply.

Bob's you uncle, bish bash bosh and your done. Sweat as a nut.
