Sony TH-M303 User Manual

Notes on MP3/WMA/JPEG/MPEG4 discs
• MP3/WMA/JPEG/MPEG4 discs (either CD-R or CD-RW) 

require a longer readout time. (It differs due to the complexity of 
the directory/file configuration.)

• When making an MP3/WMA/JPEG/MPEG4 disc, select ISO 

9660 Level 1 or Level 2 for the disc format.

• This system supports “multi-session” discs (up to 20 sessions).
• This system cannot play “packet write” discs.
• The system can only play MP3/WMA/JPEG/MPEG4 files with 

the following file extensions;
MP3:

“.MP3”, “.Mp3”, “.mP3” and “.mp3”

WMA:  “.wma”, “.WMA” and any uppercase and lowercase 

combination (such as “.Wma”)

JPEG:

“.jpg”, “.jpeg”, “.JPG”, “.JPEG” and any uppercase and 
lowercase combination (such as “.Jpg”)

MPEG4: “.asf”, “.ASF” and any uppercase and lowercase 

combination (such as “.Asf”)

• If different type of files (audio (MP3/WMA), still picture 

(JPEG), and video (MPEG4) files) are recorded on a disc, set the 
FILE TYPE setting in the PICTURE menu to the appropriate 
setting for the data to be read. (

A pg. 37)

• The system recognizes up to 150 tracks (files) per group, 99 

groups per disc, and the total number of the tracks (files) that the 
system can play is 1000. For example, if you set FILE TYPE to 
AUDIO (

A pg. 37) and play a disc that contains 500 MP3 tracks, 

200 JPEG files, and 600 WMA tracks, the system can play 500 
MP3 tracks and the first 500 of 600 WMA tracks.

• Some MP3/WMA/JPEG/MPEG4 discs may not be played back 

normally because of their disc characteristics or recording 
conditions.

Notes on MP3/WMA discs only
• The system supports MP3 files recorded with a bit rate of 32 – 

320 kbps and a sampling frequency of 16 kHz, 22.05 kHz, 
24 kHz*, 32 kHz, 44.1 kHz, or 48 kHz.

• If the tag information (album name, artist, and track title, etc.) is 

recorded on a disc, it appears in the file control display on the TV 
screen. (

A pg. 28)

• We recommend to record each piece of material (song) at a 

sample rate of 44.1 kHz and at a data transfer rate of 
128 (96*) kbps.

• Some tracks may be skipped or may not be played back 

normally.
* For WMA only

Notes on JPEG discs only
• We recommend to record a file at 640 x 480 resolution. (If a file 

has been recorded at a resolution of more than 640 x 480, it will 
take a longer time to be displayed.)

• This system can only play baseline JPEG files.
• Some files on a JPEG disc may be played back distortedly.

Notes on MPEG4 disc only
• The system supports the types of simple profile as MPEG4 files 

(MPEG4 SP).

• The system supports MPEG4 files recorded with the maximum 

bit rate of 384 kbps and an audio codec of G.726. (To play the 
MPEG4 file, it is required that G.726 formatted audio data is 
contained in that file.)

• The maximum size of the played picture is at a 352 x 288 pixel 

resolution (CIF).

• Some files may be skipped or may not be played normally.
