 MPEGTS stream recorded from TV by current VDR (2.2)
 Trying to transcode to H264, but same happens if just doing a simple
 stream copy of all streams
 How to reproduce:
 {{{
 ffmpeg -v 9 -loglevel 99 -i sample.ts -c:s copy -c:v copy -c:a copy -map 0
 out.ts
 }}}

 ffmpeg version 3.0.2-80.1 (SLES11 from Packman) built on 31 May 2016

 ffmpeg reports:
 video:3675kB audio:995kB subtitle:0kB other streams:0kB global headers:0kB
 muxing overhead: 10.355034% (complete log attached)

 There are a number of DVB subtitles present in this sample of the
 recording, none appear in the output stream. Muxer reports 12 subs packets
 of 168 bytes total, much smaller than they should actually be.

 5M sample attached under this ticket#

 Stream plays with correct subtitles in VLC and MPC-HC, but not in ffplay
 or Kodi.  This is an unusual issue as hundreds of files have been
 processed correctly, this is the 0.1% that strangely fails
