It sound like your dish network box or tv might have a auto format setting that is adjusting the pix on non HDTV broadcast. I will look at the manual of the tv to see.
I down loaded the owner manual and found a auto size featcher that will auto adjust the pix when receiving signal from HDMI:

Let me know if this works. When you get into the home menu and options look to see if auto format is on or off. If on turn off and that will cure your issue. If it is off than I would go into your dishnet work menu and find something simular with auto formating.
That appears to have solved it, let me watch it a little more and watch some commercials.
