Just got the Z5 and I am totally amazed and in love with it. My only annoyance so far is that it seems inable to display a 4:4 image, at least when fed through the HDMI input. Any "full-screen" discs I've tried to display only allow me the options of zooming or strecthhing, but will not lay the image out with black on the left and right side, as most displays would do. Is there a setting I'm not finding? I can't imagine that this option wouldn't exist. Help!
