Remedies/Causes
• Use a disc with MP3/WMA tracks recorded in the format
compliant with ISO 9660 Level 1, Level 2, Romeo, or Joliet.
• Add the extension code <.mp3> or <.wma> to the file
names.
Skip to another track or change the disc. (Do not add the
extension code <.mp3> or <.wma> to non-MP3 or WMA
tracks.)

Playback order is determined when the files are recorded.
