Hello all. I've been lurking here for about a year and a half but finally decided to join in on the conversation. I haven't seen this covered anywhere else so forgive me if I overlooked it. I have all 5 season sets of Everybody Loves Raymond and the box set of all seasons of Sex and the City. I keep noticing a screen flicker at intermittent points in the episodes. This usually occurs with a camera angle change, but not exclusively. Is this something that can be corrected or does it have to do with HBO's dvd production? Thanks in advance.
