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?
ffmpeg -v 9 -loglevel 99 -i C:\lngm1210h.mpg -s 1280x720 -aspect 16:9
