video playback

[l36pontiac]

i have a sprint touch pro 2 and im trying to play avi files of top gear. im using divx and its really crappy the sound doesn't match the mouth movement and playback acts like its stopping and going. i can play youtube video crystal clear. i have stopped all programs running in the back ground also thinking they were bogging the phone down. is their a codec for win media player to play avi?
