Comment (by smallishzulu):

 Yes, I confirm that STB has no problem. I tested both with Sagemcom and
 Techwood UHD STBs.
 I uploaded longer TS files to here:

 For TS file:
 http://we.tl/Ji2a7C2SDF

 For zip version of the file:
 http://we.tl/BJkcR8eTcg

 I run the TS files like this:
 /opt/ffmpeg/bin/ffmpeg -i /home/admintv/trt4k2.ts -vcodec rawvideo -an -f
 nut - | DISPLAY=:0.0 /opt/ffmpeg/bin/ffplay -loglevel quiet -fs -i -

 The error is here:

 When you get slice or POC errors, there is freezing and corruption in
 video.
