How do I disable automatic DivX update popups on Mac OS X
Solution from official forum. It works in my case (Setting option to NEVER fails to work)

If the URL is dead then here is the transcript
Unload the DivX auto-update and media server agents
launchctl unload /Library/LaunchAgents/com.divx.update.agent.plist
launchctl unload /Library/LaunchAgents/com.divx.dms.agent.plist
launchctl list
(com.divx.update.agent should not appear in the list)
Remove supporting DivX files
sudo rm /Library/LaunchAgents/com.divx.update.agent.plist
sudo rm /Library/LaunchAgents/com.divx.dms.agent.plist
sudo rm -rf /Library/Application\ Support/DivX/
sudo rm $HOME/Library/Preferences/com.divx.*

Go to System Preferences > DivX and modify the "Check for Updates" setting to Never.
It seems the new way is to go to Applications->DivX (folder)->Preferences
, run that and change the settings for auto-updating.
