Remedies/Causes

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.)
Do not use too many hierarchical levels and folders.
The playback order is determined when the files are

how the tracks are recorded on the disc.
