There's a selection for "Motion Steps" in the render settings. That will look at the motion vectors more during the frame and smooth out non-linear motion.

If you need a color vector pass, La Maison has a shader for Reelsmart and the Production Shaders also have a vector shader. Reelsmart does not use the blue channel I believe.

Have to keep in mind that post blur just smears pixels basically. So objects behind something that is blurred get covered by the smeared pixels.
