I may have figured out why there is a discrepency between what I think looks like a good hue and what you used. Also, this would tell me that when I encode it, it's going to be darker (more reason for my added gamma correction) Discussion can be found here:

What I'm wondering now is if your screencaps on the fanedit site are from the Avisynth script or from the encoded DVD. I'm assuming the encoded DVD, but I want to make sure.
I'll play around with the Colormatrix() plugin and try some test encodes.
