generally improves with higher bit rate-
s. In order to achieve a reasonable lev-
el of sound quality, discs recorded with
a bit rate of at least 128 kbps are rec-
ommended.

kbps, VBR (Variable Bit Rate)
The MP3/WMA player does not play
back MP3/WMA files from discs re-
corder using packet write data transfer
(UDF format). Discs should be re-
corded using “pre −mastering” software
rather than packet− write software.
M3u playlists are not compatible with
the audio player.
MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the au-
dio player.
The player is compatible with VBR
(Variable Bit Rate).
When playing back files recorded as
VBR (Variable Bit Rate) files, the play
time will not be correctly displayed if
fast−forward or reverse operations are
used.
It is not possible to check folders that
do not include MP3/WMA files.
MP3/WMA files in folders up to 8 levels
deep can be played. However, the
start of playback may be delayed when
using discs containing numerous lev-
els of folders. For this reason, we rec-
ommend creating discs with no more
than two levels of folders.
It is possible to play up to 192 folders or
255 files on one disc.
