Problem with Adobe Encore and .avi file

I’m trying to author a DVD in Encore CS4. I have everything ready except whenever I try to load one asset, an .avi file, the audio track loads but the video track does not. The video plays in vlc, but encore doesn’t recognize it. Do you guys have any idea as to how I might get Encore to recognize both the Audio and Video track?

This .avi file is one of a batch of .avi (Hajime no Ippo season 1) and the other 9 files I’m trying to burn worked fine. It’s just this one. I tried running Vid-Fix++ or whatever it’s called, and that didn’t do the trick. I’m running out of ideas.
