I can't get Netflix to display 4:3 content properly on the PS3. Playing back 4:3 content on a 16:9 TV, the PS3 stretches the content to fill the screen. The same content on the XBox is displayed properly in 4:3 pillar-boxed with black bars. When playing back the video, there are no 'stretch' options on the PS3 either. Am I missing something or is this a PS3 limitation?
