you can set divxg400 to "always load" if you want it to show up any time you play a movie.
I would recommend that you disable it completely though.
to easily access divxg400's settings, you can create a shortcut with the following command line:
Code:
C:\WINDOWS\System32\rundll32.exe [pathtofile]DivXG400.ax,Configure
(note: the [pathtofile] is not necessary if divxg400.ax is placed in the system32 directory)
