Can someone enlighten me as to this particular ailment. What exactly is it? How do I know if I've got it? How can I get rid of it? Is it the kiss of death that most people reckon it is or is it so microscopically small that only flat-earthers can see it? Answers with particular relevance to a Sony VW11HT PJ, Grayhawk screen and conponent/progressive PAL and NTSC would be very much appreciated.
