Sungale DVD Players Don't Do MP3

Does anyone have a fix for the MP3 playback function on Sungale
DVD players?  I have the model 8208, it has the often-reported
background noise (rumble/rattle/etc) in MP3 playback, on about
50% of songs.  

Has there been any kind of fix reported for this problem?  I use
mine mainly for Karaoke functions, but would also like to be able
to play MP3s.

best regards,

Martin
