does anyone else have this problem with a 36zp48? whenever the majority of my screen is bright white - explosions and the like.. the geometry changes - maybe from widescreen to 4:3 or to superlive or osmething. this doesnt happen if i turn off the auto-format modey thing, but whats the point in that it happens on different inputs. any thoughts? it seems to me that the large amounts of white (high voltages maybe??) are confusing the auto-change thingy.. didnt happen on the same dvds, same dvd player on my old tv..
