Causes
No MP3/WMA tracks are
recorded on the disc.
MP3/WMA tracks do not
have the extension code
<.mp3> or <.wma> in their
file names.
MP3/WMA tracks are not
recorded in the format
compliant with ISO 9660
Level 1, Level 2, Romeo, or
Joliet.
The track played back
is not an MP3/WMA
track (although it has the
extension code <.mp3> or
<.wma>).
Readout time varies due to
the complexity of the folder/
file configuration.
Playback order is determined
when the files are recorded.
This sometimes occurs
during play. This is caused
by how the tracks are
recorded on the disc.
The current disc does not
contain any MP3/WMA
tracks.
This receiver can only
display alphabets (capital:
A – Z), numbers, and a
limited number of symbols.
Remedies
Change the disc.
Add the extension code
<.mp3> or <.wma> to their
file names.
Change the disc.
(Record MP3/WMA
tracks using a compliant
application.)
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
hierarchies and folders.
Insert a disc that contains
MP3/WMA tracks.
