Comment (by microchip):

 You want me to provide the full mencoder command line to soft-telecine a
 progressive 23.976fps content? Because I don't know what else to provide.

 {{{
 mencoder input-24p.avi -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=3000
 -nosound -of mpeg -mpegopts format=dvd:tsaf:telecine -ofps 24000/1001 -o
 output.mpg
 }}}

 What the above will do is make the 23.976fps input seem as if it's encoded
 at 30000/1001. The output is still progressive, but with a soft-telecine
 flag set so a NTSC DVD player will handle it correctly.

 When played back by mplayer, it will correctly recognize the soft-telecine
 and will print a message about switching frame rate.

 That's basically the feature I want supported by ffmpeg's telecine filter
 (if possible). If not, maybe implement it at the muxer level and add an
 option to flag it as soft-telecined
