Movie piracy...

Many movies are pirated using a camera in theaters. Maybe some of you don't know that any camera "sees" infrared light. To test it, pick your camera and aim a remote (your tv remote is ok) at it. You will see the infrared L.E.D. blinking. Well.. I was thinking... What if many infrared leds will be put behind the projecting screen in theaters? The IR light won't be seen by people. But it will appear in recorded videos :) Obviously this could be defeated putting an IR filter on the cam lenses.. but that's the road imho :)
