Sony Dvd 5 Disc Changer 2002 I Have A Question About My DVD Player?

I have a question about my DVD player? - sony dvd 5 disc changer 2002

I have a 5-disc Sony DVD changer, DVD's and playing well, but when playing audio CDs will be moments for one or two seconds in the middle of a stretch to play then go to break, and sometimes can be five or six times during CD playback ... after cleaning the laser lens. Somebody has an idea of the subject, and how can I solve this problem?
