I spoke with Mark over the weekend, and he was going to try and find out, but I guess he's been a bit busy to post here or hasn't heard yet.
Besides the banding, my current replacement has bad startup convergence which I find quite annoying. I've also noted that the Lamp Mode and Film Projection Mode's have bearings on the size, intensity, and coloration of the banding, so it's not only a potential optical/physical issue it would appear...I will post some update photos.
