Comment (by electron.rotoscope):

 Original and modified file now attached as suggested. I've just checked
 and the file without the flag will not import into a DVD authoring
 program, the file with the flag will.

 I notice that DGPulldown changes what MediaInfo calls "Time code of first
 frame" from 00:00:00:00 to 00:00:00;00, but as far as I know this is NOT
 necessary for DVD authoring.

Comment (by mbat):

 I've experienced an apparently identical issue with recent ffmpeg builds
 (Zeranoe, 2015-02-03).
 Would be useful to know at least a workaround for the issue, of course a
 fix would be great.

Comment:

 I removed both attachments because their license is not compatible with
 the relevant files from FFmpeg (LGPL vs GPL). Both can be found easily.
 If you are interested in this feature but cannot supply a patch, maybe
 attach two short m2v samples that show the difference with similar /
 identical content? Ideally by encoding with FFmpeg and later changing the
 output file as explained in your post.

Comment (by electron.rotoscope):

 The relevant code in mencoder seems to be lines 2468 - 2491 of
 \libmpdemux\muxer_mpeg.c in today's tarball and they used the code from
 [http://neuron2.net/dgpulldown/dgpulldown.html DGPulldown] which is a GPL
 program. The code in mencoder starts with: `/* excerpt from DGPulldown
 Copyright (C) 2005-2006, Donald Graft */`
 I think it would be useful to add this feature to all MPEG-2 encoding, not
 just MPEG-PS, as some authoring programs only take raw .m2v files. I know
 this is possible, DGPulldown can add the flags after the fact as a
 separate process.
