I haven't used it but it seems to do what you are looking for.

Here's a couple of things to try from dejanews on the WMV file.


1: Make sure your Pocket PC is connected and ActiveSync is visible on the PC
screen
2: On your PC open the file explorer
3: Navigate to the folder which contains the file you want to transfer to
the PPC, leave that folder open
4: Click on the Explore button in ActiveSync, Click on My Pocket PC, then
open the My Documents folder, leave that folder open also
5: Go back to the open folder in your PC's file explorer, highlight the file
you want to transfer, then choose copy from the edit menu
6: Go back to the open My Documents folder in your ActiveSync explorer and
choose paste from the edit menu
7: You will see the Copy and Convert dialogue box showing you the progress
of your file transfer.
8: When the transfer is complete open the file with MediaPlayer 7.1


Some video and audio formats are not support in PPC MP 7.1. Goto options and select "Play unsupported video codec" and it should work.
