Additional MP3/WMA Information

An internal buffer provides ESP (Electronic Skip Protection) to virtually eliminate skipping.

When playing a disc recorded with regular audio files (CD-DA or .WAV) and MP3/WMA files, the unit will play the MP3/WMA files only.

Only MP3 files with filename extension (.mp3) can be played.

Only WMA files with filename extension (.wma) can be played.

Do not attempt to play discs which contain NON-MP3/WMA files with the MP3/WMA extension.
