Thanks for the link to stackexchange. Reading this post and others
(also the discussion on ffmpeg from when they switched from PAR to
SAR) I think the formula:

"Yet, with DAR = SAR * PAR

HDV 1080i:   16/9 = (1440/1080) * (4/3) = 1.7778
HDV 1280p:  16/9 = (1280/720) * (1/1) = 1.7778"

is more correct to write it (for ffmpeg and CinGG):

DAR = Width/Height * SAR

that is, the (4/3) and the (1/1) are now the SAR and not the PAR.

So it is no longer spelled PAR, but always just W/H and SAR. SAR, at
this point, is a "pixel aspect ratio"
I tried changing the txt (version 4). Do you think it is okay? It is
likely to be wrong.

For videos, can I ask you to do 2 and 3? I have never used and don't
really understand how DVD/BR works; and I haven't had players/burner
for a long time.
