Comment:
The file contains two programs: 59352, low resolution, works fine and is
~26 seconds long.
The problematic program is 59328, high definition (1920x1080), it contains
~26 seconds audio starting with timestamps ~34616. Audio can be played
with ffplay -vn, mplayer -demuxer lavf -novideo and can be converted with
ffmpeg.
Video is ~24 seconds, and start with 34618 when played with mplayer
-demuxer mpegts -nosound (and seek back).
FFmpeg initially sees video timestamps of 1317472613.58 leading to startup
delay and failure because of too high drop count. (The wrong timestamps
are not reproducible with ffprobe.)

Cutting the file like this solves all problems:
{{{
dd if=Brazil.ts of=test.ts bs=1M skip=72
}}}
Cutting only 71M does not really help.
