Jeep GRAND CHEROKEE WK 2022 Owner's Manual page 179

If you record a disc using a personal computer,
there may be cases where the Blu-ray™ Disc player
may not be able to play some or the entire disc,
even if it is recorded in a compatible format and is
playable on other players. To help avoid playback
problems, use the following guidelines when
recording discs:
Open sessions are ignored. Only sessions that

are closed are playable.
For multi-session CDs that contain only multiple

CD-Audio sessions, the player will renumber the
tracks so each track number is unique.
For CD Data (or CD-ROM) discs, always use the

ISO-9660 (Level 1 or Level 2), Joliet, or Romeo
format. Other formats (such as UDF, HFS, or
others) are not supported.
The player recognizes a maximum of 512 files

and 99 folders per CD-R and CD-RW disc.
Mixed media recordable DVD formats will only

play the Video_TS portion of the disc.
If you are still having trouble writing a disc that is
playable in the Blu-ray™ Disc player, check with the
disc recording software publisher for more
information about burning playable discs.
The recommended method for labeling recordable
discs (CD-R, CD-RW, and DVD-R) is with a
permanent marker. Do not use adhesive labels as
they may separate from the disc, become stuck,
and cause permanent damage to the DVD player.
Compressed Audio Files (MP3 and WMA)
The Blu-ray™ Disc player is capable of playing MP3
(MPEG-1 Audio Layer 3) and WMA (Windows Media
Audio) files from a CD Data disc (usually a CD-R or
CD-RW).
The Blu-ray™ Disc player always uses the file

extension to determine the audio format, so
MP3 files must always end with the extension
".mp3" or ".MP3" and WMA files must always
end with the extension ".wma" or ".WMA". To
prevent incorrect playback, do not use these
extensions for any other types of files.
For MP3 files, only version 1 ID3 tag data (such

as artist name, track title, album, etc.) are
supported.
Any file that is copy protected (such as those

downloaded from many online music stores) will
not play. The Blu-ray™ player will automatically
skip the file and begin playing the next available
file.
Other compression formats such as AAC, MP3

Pro, Ogg Vorbis, and ATRAC3 will not play. The
Blu-ray™ player will automatically skip the file
and begin playing the next available file.
If you are creating your own files, the recom-

mended fixed bit rate for MP3 files is between
96 and 192 Kbps and the recommended fixed
bit rate for WMA files is between 64 and
192Kbps. Variable bit rates are also supported.
MULTIMEDIA
For both formats, the recommended sample
rate is either 44.1 kHz or 48 kHz.
To change the current file, use the remote

control's or Blu-ray™ Disc player's button to
advance to the next file.
Disc Errors
If the Blu-ray™ Disc player is unable to read the
disc, a "Disc Error" message is displayed on the
rear screen and Uconnect system displays. A dirty,
damaged, or incompatible disc format are all
potential causes for a "Disc Error" message.
If a disc has a damaged track which results in
audible or visible errors that persists for two
seconds, the Blu-ray™ Disc player will attempt to
continue playing the disc by skipping forward one
to three seconds at a time. If the end of the disc is
reached, the Blu-ray™ Disc player will return to the
beginning of the disc and attempt to play the start
of the first track.
The Blu-ray™ Disc player may shut down during
extremely hot conditions, such as when the
vehicle's interior temperature is above 120°F
(48.9°C). When this occurs, the player will display
"High Temp" and will shut off the rear seat displays
until a safe temperature is reached. This shutdown
is necessary to protect the optics of the Blu-ray™
Disc player.
