Has anyone been able to get the horizontal and vertical screen position settings to do anything? Maybe Im doing something wrong but they seem to have effect no matter what I put them on. The Voom box is set to output 1080i and my tv locks into full with that input but I thought the box's position settings would be independant of that. The screen is just a little off center to the right and Id like to correct it. Its not too bad when watching something but I notice it when the menus are pulled up.
