Here's the problem - I've just got the official 2GB SD card & have been playing around with movies, pictures & music. Now everything seems to work fine except... when the Wii doesn't support the file it shows up a question mark (for movies) or a file with _before it, e.g _07 Back to Black.mp3. This MP3 file format is not supported... but below it is the same MP3 track but it does work fine. Same thing happens with the movies, a doubling up, one file works the other says it doesn't support it, illustrated with a "?"... anyway I've cleared the memory card of everything but I'm still left with these '?' not supported files on the card when I go into the Photo channel & also non supported MP3 files as well, strangely the Photos display & delete perfectly. Any ideas of how to get rid of them? or in fact avoid them in the first place. I can't understand the MP3s at all. They all worked fine but all duplicated an unsupported file with each one. Why???? Help, please.
