The current display aspect ratio is of 720 / 480 * 128 / 81 = 64 / 27. So it's
exactly two times bigger than the good DAR.
The pixel aspect ratio is 'filled' in by the mpeg2dec library and then copied
over by the plugin in the handle_sequence() function. The values returned by
mpeg2dec are:
width, height: 720, 480
picture-width,height: 720, 480
display-width,height: 540, 480
pixel-width,height: 128, 81

Something which might be of interest, is that mpeg2dec is saying that the
sequence is PAL and not NTSC.
