You're probably missing the codecs

Get GSpot.. it's free and it will tell you what you need to play a certain file.. just open the file in GSpot and it will tell you.

Another free prog you might want to try.. it will play almost anything, codecs come with it.. (very plain, no-nonsence, but it works a treat)
