Motion Blur?

[Augustine864]

I bought a cheap $350 32" Sylvania LC320SSX at BJs for my school apartment bedroom. I'm not looking for anything fancy by any means, but I've noticed some motion blur while watching things with heavy movement. A little bit but not bad while watching "The Hurt Locker" but primarily while playing Modern Warfare 2, especially if I focus on a picture hanging on a wall while I'm sprinting, for example.

Is this because it is 60hz as opposed to 120hz or is it a byproduct of the "clear pix plus engine"? I'm within the 30 day window for a return to BJs but I only want to do it if its because of the clear pix. I'm not in a place to buy anything more expensive than $350 at the moment so if its a 60hz vs 120hz I'll probably just have to live with it.
