#2689: TS Reader shows 1:1 Aspect Ratio on HD content

Source material does not matter.
Any HD content done at standard resolutions (1280x720 or 1920x1080)
displays as "Aspect Ratio: 1:1" in TS Reader. TS Reader is showing what
most set-top boxes show.
I have found that adjusting the resolution to an "incorrect" resolution -
e.g. 1270x720, or 1290x720 - fixes the issue, but that is not a solution.
The only difference in the CLI output generated by ffmpeg is the SAR,
which is 1:1 when 1280x720 is the size selected, and a different value
when an "incorrect" resolution is specified. Could there be a flag that
ffmpeg is setting at 1:1 which should be 16:9?
