My 5 DVD Magnavox would not play DVD’s unless the were perfect. It was so frustrating but I could tell it had a lot to do with the laser being dirty. I tried one of those CD’s with the cleaning brushes. Still would not work,finally I took the the stupid thing apart and reached way in there and cleaned it by hand. Just like that it started working again. Unfortunate I have to repeat it about every three mouths. It will be my last Magnavox!
