I think this might be a limitation that comes with mental ray.
It needs to calculate motion blur based on information it calculates from the previous frame.
We are finding its very hard to get the correct result on shots that have fume at frame '1' and also getting a correct result rendered on the final fame of a shot (if fume present) without rendering a extra frame 'plus one'
and so rendering a 'scrap frame' so the last one renders correctly.
An FYI in case it helps.
