I download movies from iTunes onto my computer and then play them (through the computer) on the High Def TV (Sony Bravia Smart TV)... I've got the computer hooked to the TV through VGA. The computer is doing all the work with respect to generating the image and so forth so wondering if HDMI will give me anything better irregardless if the movie is in HD or SD. I'm sure a few here will know that answer. Thx in advance.
