SOLVED: 9:32? aspect ratio bug on roku streaming stick

Let's try repackaging the video.  Is this file an MKV file?  If so, use this command.

Code:

ffmpeg -fflags genpts -i "/path/to/video.mkv" -map 0:v -map 0:a -map 0:s -map_chapters 0 -c:v copy -c:a copy -c:s copy outputFile.mkv

Yes the files are mkv. Where am I supposed to enter this command?
