Mmh... did you use my settings for the "Exorcist"-filter? Because your image still contains some halo... though I am sure they are the result of your sharpening filter applied, because this time they're on both sides. Maybe you should try the Xsharpen approach (which means scaling the image up to something like 2000x1000, applying that filter, and scaling it back, down to 720x480. The filter sharpens by another method, which won't induce halos). But while my method doesn't produce halos, I've gotta admit that your method very nicely sharpens the detailed areas (although there's some combing visible):

Of course my levels are a little different (but yours are better... I haven't spend much time on my color). But note that I haven't used a noise filter at all (and I still don't think it's necessary... the film-grain adds a little detail, and if you're going for a dual-layer-disc, you won't have to worry about compression, I guess).
