My neighbor has a Pioneer 16:9 set (I think it's the 53"). Anyway, he's having some trouble. I think he watches all widescreen movies in Full mode and he's getting some vertically squished images when he's watching a non-anamorphic disc. I know nothing about the modes on a 16:9 set, and he said the manual really doesn't do a very good job of explaining the different modes. What mode should he use when watching non-anamorphic discs? Your help is appreciated.
