I'm probably quite a few years away from replacing my 4x3 RPTV. Nevertheless, I dropped by a decent home theater shop in Sacramento. All the sets that were displaying broadcast programs had the screens filled with a distorted flattened picture. The salesman claimed that they did not use the windowboxing feature because that would burn in the vertical borderlines. What gives? Was the store wrong, or do you folks with 16x9 sets crop or distort full screen programs, rather than use the windowbox?
