Thanks
Keru for recommeding me this beautiful All in One DivX Codec Pack.
This is freely distributed under GNU Public License version 2.
I was using Nimo Codec Pack. But This proved to be better and safer.
Once installed, it will automatically update to the latest version (provided that you allowed it to do so.)
No spyware; No imcompatibilities; No conflicts. Works great.
