wmv on pocket pc

I have a wmv on my pocket pc and windows media player and it wont play. I have one one their all ready and it works fine

 

Do you get an error message? Does the one that won't play work on your desktop/laptop PC?

 

I had a problem where the sound wouldnt play then I encoded for pocket pc using windows media encoder then it worked just fine. Maybe your having a similar problem even if its not just the sound.
