No, no, I'm talking about the fuzziness of the HDR image.... centering 
the HDR image at the camera location helps, but won't make it any 
sharper. Since the light probe is a certain size (in pixels) there will 
always be blending between pixels, causing the image to look fuzzy. A 
higher-res light probe would fix it, but these aren't always available. 
Scaling the whole composited image down would also do the trick, but 
small images aren't much fun to look at.

The best thing I can think to do is model a ground object with a new 
texture, and blend it into the HDR image using focal_blur. The 
blur_samples don't even need to be high.... a value of 10 would work.
