Solved FLV file plays sound but no video?

[Minh1234]

I downloaded a FLV file. It is small and it only plays souns on the WMP. I change the format to mp4 and it cannot play at all. When i change to AVI it only plays sound. How can i fix this?

im thinking that you will need a flv codec to play them on wmp or wmc, you could use vlc mediaplayer which has the codecs built in rather than install codec packs in windows.
