Subject correction - "A3" Before D* MPEG-4 LIL Channel Description Just curious.. I noticed this morning that if I look in the Guide and look at my MPEG-4 HD LILS, that there is an "A3" before the channel description above the Guide. I am in the Harrisburg/Lancaster, PA market using an HR20. Anyone else seeing these with their locals or in this area. What does "A3" mean?
