i want to upscale a 4:3 dvd to 1080p without it stretching on my blu ray player how

Even if you keep your AR settings to original, HDMI output WILL BE 16:9 native by default on a HDTV display. Unless your player has an option for the AR of SD/DVD material, then its stretched into 16:9 no matter what. One option is to set your HDTV to a 4:3 when watching 4:3 DVDs, but then that make things like native widescreen menus and anamorphic content squeezed and strange looking.
