iDVD "There was an error during movie encoding."
I have MBP with iDVD and I'm running OSX 10.6.8. I have been trying to burn a DVD which is in mp4 format and plays in Quicktime and iDVD. However, after rendering the error message pops up. I am not very computer savvy, any clearly explained help is appreciated. Thank you.
MacBook Pro, Mac OS X (10.6.8)
