Video smears and isn't properly viewable in Articulate Encoder

I am trying to crop a video using Articulate Encoder (tried both a SWF and MP4 file), but the video is distorted so I can't effectively crop it.  The video looks like it gets smeared diagonally so that there are just streaks of colors instead of my actual video.  Interestingly enough, when I crop a random piece off it and publish the distorted video, the published file looks and plays as it should.

Has anyone had this problem before?  I'd really like to be able to see the video intact while using Encoder so that I can crop it properly.

Thanks!
