Comment (by alexpigment):

 oromit: Not to hijack this bug, but it works with Staxrip. As you said, it
 "seems to be implemented" in FFMPEG from what I can tell, but the
 resultant video seems as if half of the fields are being thrown away. In
 other words, it's got the temporal resolution of 30p but with combing
 artifacts.

 For what it's worth, MediaInfo shows a field that says "Original Frame
 Rate: 59.940 (60000/1001)FPS" - which seems a bit odd considering the
 source video in my test is 29.97 interlaced. The working video from
 Staxrip doesn't have that same field at all.
