Ok i think i've understood that
there is a set up button on the remote that goes to a preferences set up, on this there's a TV display option that goes from Normal P/S (pan&scan)
Normal L/B (letterbox) and Wide (d'uh)
i tried playing Terminator 3 which i think has an AR or 2:35:1?(but it's defo a widescreen rip) in every option but it still comes out as a widescreen showing, on my TV this can then be stretched a bit with the zoom function giving it about an inch more height either way without much distortion (if any) and there's also a zoom fiunction on the yamada but that just kills the pic completely and you lose a huge amount of screen
for this movie it was best viewed IMO widescreen format on yamada and zoom function on TV to give the largest viewable area without distortion
hope that has answered your Q and you understood my answer
