The file could be fake, check it out with GSPOT, here's the link:-

GSpot Codec Information Appliance

This handy little utility will identify the kind of file you have.

OK, if the file turns out to be real then you may need additional codecs, here is another link:-

XP Codec Pack

Download XP Codec Pack 2.3.3 - XP Codec Pack is one of the most complete codec pack


Vista Codec Pack

Vista Codec Package Download - Softpedia

You've not said which O/S you have so I have directed you to both XP and Vista.
