This might be a common question, so please bear with me. I purchased a 2 gig SD card for use with the Wii. Being stuck with a Mac at the moment I am forced to convert my iTunes into MP3s. I can do this no problem, and it shows that I have the files on my SD card. When I put it in the Wii and go to select a song while playing Excite Truck, about 1/3 of the MP3s appear and the ones that do have duplicate files that play nothing. Little help anyone?
