Comment (by cehoyos):

 Which capture device produced the input video?

 I tested the following command lines:
 {{{$ ffmpeg -i
 Ffmpeg_duplicates_and_drops_frames_when_given_a_ts_stream.ts -qscale 2
 -mbd 2 -vcodec mpeg2video out.ts}}}
 {{{$ ffmpeg -i
 Ffmpeg_duplicates_and_drops_frames_when_given_a_ts_stream.ts -qscale 2
 -mbd 2 -vcodec msmpeg4 out.avi}}}
 {{{$ ffmpeg -i
 Ffmpeg_duplicates_and_drops_frames_when_given_a_ts_stream.ts -vcodec mpeg4
 -acodec aac -qscale 2 -strict -2 out.mp4}}}
 Imo, the three output files play smooth with WMP but the dropped frames
 are visible with frame-stepping. I suspect the problem is a non-constant
 pkt_dts_time in the input file.
