Picture of divx movie is in negative

[Quietseb]

divxg400 will show a small blue screen in the systray when loaded
right-clic on it, select divxg400 in the popup menu to access its config

DirectVobSub will show a greenish curved arrow in the systray when loaded. right-clic on it, select directvobsub in the popup menu to access its config

if in doubt, you can search your disks for files:
divxg400.ax
dvobsub.ax
ffdshow.ax

(I think you would know if ffdshow was installed, whereas divxg400 and dvobsub are often silently included in packs or software installs)

If you wan't to access one filter configuration at any time, you cantry and create a shortcut with the following command line:

rundll32.exe "[PATH_TO_AX_FILE]",Configure

or

rundll32.exe "[PATH_TO_AX_FILE]",configure

(the c or C depends on the filter/filter version)
