Please elaborate about what you mean and or post a patch

iam not trying to look for anything, iam just trying to fix bugs
and as is ffmpeg displays the wrong DAR in the printout for the
overscan case (i belive this is a big part of the misuderstandings),
you would get bt601 with some crazy nonsense DAR
values instead of 16:9 and 4:3, this patch is intended to fix it

internally ffmpeg only uses SAR which should already be correct for
all cases

also if the patchset i posted gives the wrong values, in some case
please post an example, ill fix it
