 When converting any file to a m2v and checking the resulting file, the
 duration is not correctly calculated. mplayer shows also wrong duration.
 Quicktime and Mediainfo show the correct duration.

 example:
 ffmpeg -i fate/aletrek-rle.mov -target pal-dvd -f mpeg2video -an aletrek-
 rle.m2v
 [...]
 Duration: 00:00:03.33

 ffprobe aletrek-rle.m2v
 [...]
 Duration: 00:00:00.76

 mediainfo aletrek-rle.m2v
 [...]
 Duration : 3s 400ms

 mplayer -vo null -ao null -frames 0 -identify aletrek-rle.m2v
 [...]
 ID_LENGTH=0.77
