I just got a Samsung HT-Z310 today and am having problems setting up the upscaling. I am running it over hdmi to my tv but when i play a dvd, it plays in 720x480. It is a 1080i player. I looked all through the manual and the onscreen menus and could not find anything about setting the res for the upscaling. Does anyone know how to fix this so i could set it to the correct res?
