Some divx encoded files not playing audio

[seiswirth1]

I have a few .avi files that look like they were encoded in Divx. Problem is that they dont play sound through the PSM but will play audio from the PC. The only difference between the PC and the PSM is that I have Klite Codec installed on my machine as well. Not sure if that affects the PSM or not.

Can anyone shed some light on what I might need to do to get audio working in these files instead of downloading copy after copy until I get one that works?

Thanks
Scott
