DivX400G how do I get rid of it?

[Critical_lock]

Alot of the new encodings such as Queen of the Damned and several
copies of Lord of the Rings used the DivX400G codec as there video
codec.... The problem I am having is that I cannot seem to get rid of this
f*cking anoying codec..... I have tried TMPeG over and over again
to recode these files to VCD compliant, but no matter what I cannot
get rid of that damned codec!!!!! it keeps sticking around...
Thus the Sytem clock refference will not come out to the 1200 ratio it
needs to be makig it impossible to make VCD's out of ANYTHING that
was encoded by DivX400G....
Can anyone PLEASE!!!!!!! tell me how to get rid this rotten anoying
codec so I can encode things.
