I encountered this several times over the past few years. I live in Austin, TX, but I am originally from Houston. Whenever I go back to Houston to visit my family and friends, I notice that the NBC affiliate there "zooms" the widescreen presentation of ER on NBC to be fullscreen. It is to the point where the the names from the opening credits are all cut off and you cannot even tell what they really say. I thought this possibly could have only been because the particular episode that aired was a re-run. But, during a the season finale, I called a friend and she confirmed that her ER was shown in fullscreen while mine in Austin was in widescreen. I have never seen anything like this before. Does anyone else have an affiliate that does this?
