It seems that no matter how clean my lens is, my x box only plays the DVD's that it wants to at the time. I leave the screws out of the chassis for easy access and I clean the eye with a Q-tip and a smidge of windex. It usually clears that disk is either dirty or damaged message right up except when it comes to DVD's. I am so mad that it won't play my LOTR Return of the King. The disk is in immaculate condition. Anyone know a fix or a Mod?
