Windows Movie Maker Problem

[CodeShark]

I'm having this problem trying to Import a Movie Clip Into my Windows Movie Maker. It's a MPG format and this is what it says when I try to import it.

Also here is some information on the file that I'm trying to open, which by the way plays just fine in my Windows Media Player...

Any help would be greatly appreciated...

I've reinstalled or redownloaded the movie maker several times already, but to no avail. I think I'm missing some sort of Codec, but I don't know which one I need, how would I go about finding that out?
