If you D/L Gspot or AVICodec and open any file which wont play it will tell you which codec you need to install.

The newer mediaplayer 9 often refuses to play certain types of movies.
Try to play it first with the older mediaplayer you can find in the same dir as the Mediaplayer 9.
Search for mplayer2 on your pc.
You can also try other alternative players like mediaplayer classic.
