This discussion is about files that do not play with 
-demuxer mpegts at all, and I asked for sample files 
that do not play with -demuxer lavf (the question was 
if it is a good idea to make -demuxer lavf the default).

This file seems to play fine with both -demuxer mpegts and 
-demuxer lavf so I don't see how it is related to above thread.

Please understand that the only way to get the exact duration 
of a mpegts file is to decode the whole file.
(FFmpeg just estimates, you should get this estimate with 
.demuxer lavf)
