Since I purchased my new Panasonic BDT-220 Blu-ray player, I have been noticing an anomalie while watching Blu-rays: I am getting bizarre moire patterns every time there is a fade in or out on a bright area, rather like irregular concentric rings (is this what is called "ringing"?). There is a little less smoothness in ordinary pans, too. I have tried a few different player settings, as I can't imagine my Sony TV has suddenly started doing this after three years, but so far have not . Anyone? Thanks in advance.
