[MEncoder-users] MPlayer and MEncoder problem with a 2 second clip

I'm wondering why I'm not able to play or convert this 2-second clip with
MPlayer or MEncoder. It's telecined and interlaced 1920X1080. I used
SVN-r34422, compiled a few days ago.

Here's the media info (raw video is 60 fps interlaced):

This is a typical problem for the video I normally work with, and I'm hoping
to find a solution. VLC has no trouble with it, nor does QuickTime Player. I
can step through the 30 fps deinterlaced frames and see them correctly
through the entire clip with QuickTime Player, but when I try it with
MPlayer's "." shortcut, frames are skipped.

Here's a sample command line I've used for MEncoder, which deinterlaces and
converts to 24 fps. The reason I'm not ready to blame the video source is
that the frames skipped by both MPlayer and MEncoder aren't skipped by other
players.

"mencoder 2_Second_Clip.mp4 -o Inverse_Telecine_2_Second_Clip.mp4  -nosound
