Firefox wont play WMP videos

[dtakias]

Hi

 

I have a problem with WMP videos not playing on firefox. I am using the lastest frontmotion version and also tried running the latest Portable version from a network share.

 

WMP plugin for Firefox is already installed and WMP version is 11 on XP SP3.

 

The problem only appears under Domain accounts and not under local logons. The GUI will appear but video won't start playback! Same problem on the official plugin testpage

 

I am pretty sure it's a permissions problem but I cannot seem to find any solution to it!

 

Any ideas?

 

thanks
