It sounds like you have a corrupt MP3 file. Do you hear a slight glitch around the problem point when you listen on the PC? Software decoders are much more tolerant of corrupt MP3 files then the decoder in the Book Port. Where did this file come from?

On the BP, when I listen, a file will play correctly for about 2 minutes, then set itself back about 20 to 30 seconds and repeat, then go another 2 minutes and rewind again. The same file does not perform in such a manner on my laptop. Any ideas? Dan
