I don't see any combing at all, so I think the video is just sped up. Try slowing it down to 23.976fps in AE.
AviSource won't open it because of the codec used. Even installing the Panasonic DV codec did not help; however, VirtualDub was able to open the AVI, so I rendered it to Lagarith and then used AviSource().
EDIT: I got AviSource() to work by installing CedoCida.
AviSource()

Using DirectShowSource() on the original file seems to work too.
