I've got a Motorola 5100 digital terminal. I have it set for 1080i scan. If I watch ABC HDTV broadcasts, do I have to each time manually go into the boxes menu to change it to 780p? Or does the box convert automatically? Also will my Toshiba widescreen 57" HDX82 (or 83 - I forget) be able to pick up either through its component color stream jacks?
