Need advice with render settings...images attached

I cannot get SR to properly render this wall. The attached imaged is shown with SR Production setting. You
can see all of the aliasing on the purple wall. It renders fine when I use my own settings without SR.

Since I can only attach one image file to this post, I will attach the other rendered image to a following post.

What setting can I change in SR to increase the quality of this image?

Imaged rendered with my settings and no SR

Resent.....images were too large

I am using Mitchell-Netravali, IM & LC. When I render with SR, I have the AA filter set to "user", with Mitchell-Netravali set in my render panel.

My settings:

Adaptive DMC: 3,6
Clr Threshhold: .003
IR min: -3 max 0, HSph sub:30 Interp samples: 80
LC 2500
DMC Sampler: Adaptive Amount:.85 Global Subs: 1
