Fans sucking air into the case, and around the components pull in dust as well, something that doesn't get along very well with lasers and sensors, so they fail frequently. DVD lasers put out a much tighter beam than a CD laser, so they tend to be more sensitive to dust on the lens and emitter. -- Claude Jones Brunswick, MD, USA
