2 Questions. When adjusting the sensitivity of the sensor bar, what exactly are you doing. whats the difference between 1 & 5? the wii says there should be only 2 blinking lights. how fast should they be blinking? does any of it depend on how far away from the sensor bar you are? theres a light on the cieling behind my tv and to the left. when adjusting the sensitivity of the sensor bar, if the light is on, the upper left hand corner of the screen displays a large white circle in addition to the 2 smaller circles that represent the controller. if the light is off, the larger circle goes away. can anyone explain how/why thats happening?
