I am quite puzzeled over this because I bought a wii and everythig works and is fine, but the other day I lwas looking on youtube when I saw sombodys tv while playing a game and the sensor bar was lit up and it wasnt my eyes or a reflection because the person acturly stated the the sensor bar was lighting up. Is this because the sensor bar i have go tis the one that came with the wii rather than one bought on its own?
