I can still see moire in the bottom image... if you have PhotoNinja, try that.
I like LR4... but, in that area, just the color noise removal on photoNinja literally ripped all of the color moire out. At 100 in LR4, it was still there on the bookbag examples that I posted. If I had a full license I would export a few seconds to see what it does in motion because I feel like it shouldn't be that easy.
My feeling is that you might have missed those stills back a page, I already tried LR4, it wasn't completely satisfactory.
