Comment (by agusdallalba):

 out.mpg is 2242MB long, averaging 3393 kb/s for video + audio. However
 ffprobe says
 {{{
 Input #0, mpeg, from 'out.mpg':
   Duration: 01:28:05.76, start: 0.994667, bitrate: 3393 kb/s
     Stream #0:0[0x1e0]: Video: mpeg1video, yuv420p, 720x576 [SAR 1:1 DAR
 5:4], 104857 kb/s, 25 fps, 25 tbr, 90k tbn, 25 tbc
     Stream #0:1[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 448 kb/s
 }}}
 Note the 104857 kb/s in the first stream.

 FFmpeg complained a lot during the transcode about with {{{ [mpeg1video @
 0x1d56f40] warning, clipping 1 dct coefficients to -255..255 }}}

 I've attached the full report and a short enough sample that is
 considerably blocky after after the transcode on my setup, particularly in
 the background.
