[Cin] DAR, PAR and SAR, again

[Andrea paz]

Source_1 (and 4) I made them with "BD Render" according to Phyllis'
instructions in a previous post. Here is the result from ffprobe:

$ ffprobe -hide_banner bd.m2ts
Input #0, mpegts, from 'bd.m2ts':
  Duration: 00:01:06.91, start: 0.074667, bitrate: 10242 kb/s
  Program 1
  Stream #0:0[0x1011]: Video: h264 (High) ([27][0][0][0] / 0x001B),
yuv420p(tv, bt709, top first), 1440x1080 [SAR 1:1 DAR 4:3], 25 fps, 25
tbr, 90k tbn
  Stream #0:1[0x1100](ita): Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz,

Didn't the hdv file you passed me originally have that ".ts"? I didn't
consciously alter the file, so I can't tell you how that second
extension appeared.
