[FFmpeg-user] Transcoding 23.98 for DVD for Adobe Encore

[Bob Maple]

I'm trying to convert some files to MPEG2 for someone to drop into Adobe 
Encore, but it wants to re-transcode everything I make.  The sources are 
23.98fps.

Just doing something simple:

   ffmpeg -i Source.mov -target film-dvd Test.m2v

Encore scans the file and says it has to transcode.  If I resample the 
rate to 29.97 however, it accepts the file without transcoding:

   ffmpeg -i Source.mov -target film-dvd -r 29.97 Test.m2v

Upon looking at the first result and comparing it to a working m2v at 
23.98 that was encoded elsewhere, I notice MediaInfo shows an additional 
line of "Scan order: 2:3 Pulldown" but I'm so far not finding any ffmpeg 
options to tag things as such and am wondering if this is all that is 
throwing Encore off.

Any suggestions?
