 The user provided a sample that plays fine with mplayer -demuxer mpegts,
 shows massive A/V desync with current ffmpeg, current ffplay and current
 mplayer -demuxer lavf.
 For ffplay this is a regression since 01d4619 (can only be tested by
 merging 4dece8c, crashes without), for ffmpeg this is a regression since
 0ff4f0c.
 Until FFmpeg 0.10, -async 1 could be used as a work-around (the start of
 the output file contained dropouts but the rest of the output file played
 fine), this does not work since FFmpeg 0.11.
