iDVD 4.x: Possible solution for burning/multiplexing issues

We previously reported an issue where iDVD 4.x fails during the multiplexing stage of recording a DVD -- generally on projects that are over an hour long.

There has since been a multitude of discussion on the issue, with various suggested workarounds. The latest comes from Chris Ogle, who says the following process has resulted in no subsequent burn failures:

• If you have had failures already, close iDVD and trash the com.apple.iDVD.plist preference file in Home>library>Preferences
• Go to Network System Preference Pane and create a location which has no ports open (go to Network Port Configuration in the 'Show' popup and unselect all ports. Call this location 'iDVD'.
• Shutdown your machine (not restart)
• Disconnect all Firewire devices
• Restart the machine
• Quit any open applications (startup items, etc.)
• Open Activity Monitor (Applications>Utilities>Activity Monitor) and quit any third party background processes that are not related to the system (if you are unsure leave it running)
• Create and run your iDVD project.
