To adjust the image to the left or right, when using satellite or OTA, is it better to use the "tracking" or "horizontal" settings on X1? They both appear to do the same thing. Does either setting mess with the image quality?I use the VGA/component input for my HD satellite receiver/OTA antenna, and the S-video/component input for my DVD player. I already adjusted image with my sat. receiver as much as it allows, and I still need to move it over more. Thanks.
