.avi files???

im downloading a movie and it has .avi at the end of the file name. i tried to play a part of it( it isnt all downloaded yet) but i media player wont play the file and winamp just has a blank screen? is there something i need to do to this file before i can play it? or a specific player needed to veiw it?
thanks in advance

u may need a codec

www.dvdrhelp.com (codecs and info here)

or if u use Bit Torrent

go on suprnova.org and in the apzz section download a codec pack

Nope..........AVI movies don't play until fully downloaded.
