iLife’11 won’t burn iDVD’s
Apple – Support – Discussions – Multiplexing and burning error …. SDMacuser solves the issue:
Have you tried disposing of the plist for iDvd yet? It’s located in your Home folder (the one that looks like a house) > Library > Preferences >
com.apple.iDvd.plist
Make sure to quit iDvd prior to disposing of the plist. This procedure will not harm your mac nor the app. Lastly I’d like you to Restart your mac and try iDvd one more time. Post back if you need further help.
