File Association Assistance Needed

Hi,

I downloaded the Divx Mobile player for my tilt and it works great with my videos on my Windows Mobile 6 Pro device, however, when I try to stream a file or open it via file association instead of using Divx to open the file, my phone attempts to open the video file in Windows Media Player which will give you an error message that it cannot open/play certain media formats. Can anyone tell me how to change the file association to open Divx Player instead of Windows Media Player when I click on a video to stream it off the mobile Divx video site?

Thanks!!!
