I played a MPEG-4 video recorded on my camcorder. The video played at 4:3 aspect ratio but it’s supposed to be 16:9.

The line beginning ‘Stream #0:0’ clearly shows that although the video’s dimensions are 720x576 the video’s data says that the display aspect ratio should be 16:9.
This video plays perfectly in Quicktime and VLC on Windows. My Samsung TV also plays it at the wrong aspect ratio but has an option to manually override this.
