We have had a sumsung S221 DVD play for a while now and it had worked perfectly. Just recently we have been having problems with it. It will play burned CDs just fine and some other retail CD perfectly, but some cds when we put them in the tray will try to load and gve us a no disc error. and sometimes it will start to play the movie then it will skip and scramble the picture and make it unwatchable. we have cleaned the shiznit out of it and still are having problems. can anyone share with us what may be wrong with the player? thanks.
