Some additional programs, like The Bubbles, can be used with Hit Analyzer and allow you to create shooting range with moving target via dataprojector. But using of data projector is not as simply as it looks. There can be problems with hit detection for technical reasons:
1) The LASER is just weak. To prevent this, use at least 5mw LASER or you have to shorten the distance between projector and camera.
2) You have bad projection screens that is absorb LASER beam. To prevent this, set brightness on data projector to low (or use better projector screen).
At the end some basic advices:
Be sure that your camera is running at 30 fps and your batteries are fresh.
