MP3/WMA Format
Burning an MP3/WMA disc on a personal computer:
•
Make sure the MP3/WMA files are recorded
on a CD-R or CD-RW disc.
•
Do not mix standard audio and MP3/WMA files on
one disc.
•
The CD player (lower slot) is able to read and play
a maximum combination of 512 files and folders.
The DVD player (upper slot) is able to read
255 folders, 15 playlists and 40 sessions.
•
Create a folder structure that makes it easy to find
songs while driving. Organize songs by albums
using one folder for each album. Each folder
or album should contain 18 songs or less.
•
Avoid subfolders. The system can support up to
eight subfolders deep, however, keep the total
number of folders to a minimum in order to reduce
the complexity and confusion in trying to locate
a particular folder during playback.
•
Make sure playlists have a .m3u extension as other
file extensions might not work.
3-100
•
Minimize the length of the file, folder, or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders, or
playlists could cause the player to be unable to play
up to the maximum number of files, folders, playlists,
or sessions. To play a large number of files, folders,
playlists, or sessions, minimize the length of the file,
folder, or playlist name. Long names also take up
more space on the display, potentially getting cut off.
•
Finalize the audio disc before burning it. Trying to
add music to an existing disc could cause the disc
not to function in the player.
Root Directory
The root directory of the CD-R or CD-RW is treated as
a folder. If the root directory has compressed audio files,
the directory is displayed as F1 ROOT. All files contained
directly under the root directory are accessed prior to any
root directory folders. However, playlists (Px) are always
accessed before root folders or files.
