Help Divx avi files on Droid X

[turboman1531]

Just got my X last week and have been playing around with it quite a bit. Last night, I downloaded some divx movies and transferred them to the phone....tried playing them, but the player (default player...don't know name) just freezes...after a minute, I get an error 'file cannot be displayed or played'.. i thought maybe I had a bad download, but i've tried 6 different movies....all play on my laptop.... what am i doing wrong? any suggestions would be much appreciated. Thanks.
