>have to manually change the aspect ratio because it wasn't able to figure it out on its own. For HDMI connections, this isn't the TV's fault (actually I think my TV doesn't even let you change the aspect ratio for HDMI inputs.) For SD component/composite, there is no aspect ratio information in the signal so the TV cannot determine it correctly and generally defaults to assuming 16:9 because most people stupidly prefer 4:3 content to be stretched to 16:9.
