Problem playing CD's with Symphonic CD5800

I have a problem playing CD’s with my CD player (Symphonic CD5800). I can copy Original CD’s and the play fine, but if I copy tracks from an alternate source (download) or compile to another CD it won’t play no mater what the format (MP3, WAV. WAM) I choose. Any suggestions? or is there a product I can purchase to copy CD’s in order to make the CD player think it’s original?
