I have the same hardware and is working fine with David, scanniing at 60fps.
About speed of the projector, take in mind the Hz: usually they work at 60Hz with VGA connectionm and faster with HDMI (till 120Hz if I am right).
So this Hz value will give you the speed of the projection.
About CMOS vs CCD, as Ed. wrote, nowdays there are no relevant differences and for the 3D scanning CMOS are good as the CCD sensors.
