Just my 2¢, but the wavy lines issue I've seen on one of my early scans, but usually it was with the turntable, and it happens when you have a shallow viewing angle on start up. If I rotate the model on the turntable and scan again it doesn't do it the same.

PS. I think the native resolution of the projector is 1024x768, but it's pulled down to 800x600 for the software screens.
