Hi there. I was nervous when I heard about the double layered disc problem for wiis, as my wii was made in 2006 and is one of the older ones. however, when i stuck it in my wii, it played perfectly! however, now that i play it, it still plays fine but I hear these really loud things coming from the disc drive-that don't sound normal. It's like the disc is struggling to be read. This may foreshadow future problems. I can live without my wii for a week. do you think it's worth getting the lens replaced?
