Simply select the 'DivX Plus DirectShow Filters' from the list and click the Remove button. Your first option is to use the 'Add or Remove Programs' function in your Control Panel. If you have already installed these with the DivX 7 for Windows software but would like to remove them, you can do so in one of two ways.

(The Installation Wizard will prompt you through each step.) Please keep in mind, however, that the DivX Plus HD DirectShow Filters for decoding MKV/H.264/AAC are set to a Low Merit so they should not override any other decoders or MKV file splitters set as the defaults on your system. If you do not want to install the MKV/H.264/AAC DirectShow Filters on your system, you can simply unselect them from the list at the appropriate step in the installation process. What if I don't want to install or want to uninstall the H.264 DirectShow Filters? That's it! If your Serial Number disappears and the registration status changes to 'Registered', your DivX software is registered and ready to use! Enter your Serial Number in the space provided and click the REGISTER button.Go to ALL PROGRAMS > DIVX > DIVX CODEC > REGISTER PRODUCTS.
