I have yet to be able to burn a full dvd in iDVD. Everytime i try it either hangs on the Multiplexing and burning phase forever (iDVD 3) Or Unexpectedly quits toward the end of the Asset Encoding phase.(iDVD 4) This is extremely frustrating. And has happened on numerous projects that i need to get done. iDvd seems to work fine on all of my friends computers but mine is another animal. i have a 17" inch G4 iMac with 512 of RAM. Would more RAM help this? Possibly moving the source files to another hard drive? I have tried both encoding types (60 and 90 minute) but get the same results either way. Any help with this will be greatly appreciated.
