The file claims to be written by FFmpeg.

You cannot put ass into mpegts.

Your input file is NOT interlaced, it is telecined, use an inverse
telecine filter. Every deinterlacer permanently damages your video, in
theory an inverse telecine filter creates perfect output.
Both pullup and fieldmatch seem to work ok for your sample.

The following works and keeps the Closed Captions, it may not
work correctly with the inverse telecine filter though:
$ ffmpeg -i input -acodec copy -vcodec lib264 out.ts
