Thanks for the tip, Ronnie. This is a classic example of the type of help we need, to survive in this business. If we can collect more of these HDTV tips, we will be better prepared when the time comes for us to face the newer sets. You guys build my confidence, when you make posts of this quality ! Keep up the good work.
