* The elapsed playing time may not be 

displayed correctly depending on the MP3 
audio tracks.

• The following discs/situations can increase 

the time it takes to start playback:
– a disc recorded with a complicated tree 

structure.

– a disc recorded in Multi Session.
– a disc to which data can be added 

(non-finalized disc).

– when the tracks in another folder have just 

been played back.

• When the disc is loaded, the system reads all 

the tracks on that disc. If there are many 
folders or non-MP3 audio tracks on the disc, it 
may take a longer time for playback to begin 
or for the next MP3 audio track to start 
playback.

• You are recommended not to save other types 

of tracks or unnecessary folders on a disc that 
has MP3 audio tracks.

• The system can only play back MP3 audio 

tracks with the extension “.MP3”.

• Attempting to play back non-MP3 format files 

that have the extension “.MP3” may result in 
noise or malfunction.

• A folder that does not include an MP3 audio 

track is skipped.

• The system can recognize up to

– 256 folders (including the root folder).
– 511 MP3 audio tracks.
– 512 MP3 audio tracks and folders on a 

single disc.

– 8 folder levels.

• Depending on the encoding/writing software, 

recording device, or the recording media used 
to record an MP3 audio track, you may 
encounter problems such as cannot play back, 
sound interruptions and noise.
