When opening a XviD file in Gspot I'm getting this message in the 'Status' box: Codec Status Undetermined.

It happens with each and every XviD I throw at it. The info in the Gspot-window seems all OK.
I've tried un- and re-installing the latest XviD-codec several times but to no avail.
Is there anything else I can do to rectify?

Thank in advance!
