Adjusting screen on HD TV

Question

When I am watching a non-HD program the screen is expanded where I can not see the score or ticker-tape that is running at the bottom of the screen. Example: when I am watching a football game in non-HD I often can't see the small box at the top of the screen that shows the score. I also can not see the scores that run in ticker-tape fashion on the bottom of the screen. However, if the game is in HD I do not have a problem seeing the box score and scores running on the bottom of the page. I have tried to play with the picture mode (cropping, zoom etc) but am not having any luck with adjustments.
