I have just got a pioneer 575-S dvd player to go with my Toshiba 26WL46 LCD TV. I am running the DVD player in progressive scan mode. I've watched a few films so far on it, but two of the three i have watched have shown some flicker on objects such as checked shirts, walls and such like. The DVD's showing this so far are Nightmare Before Christmas SE and Around The World in 80 Days (2004). I watched Shrek 1 and 2 the earlier and neither of those showed any of these problems. What causes it? Can't I fix it?
