Kurt: These are files which are not currently supported. They are files with an 8KHz sample rate. You can copy them directly to the Book Port and play them if you wish.

If I hit spacebar and continue it goes to the next one. Are these bad MP3 files or corrupted or what? Are they also tied to the fact that some MP3 files do not put the whole file, only a piece of it? Thanks. Kurt
