I too had a bundled version of WinDVD Creator 2 that had quirky problems. At InterVideo's suggestion, I downloaded and installed their trial version available from their web site. At first, it seemed to run better, however a crash while using their software caused me to loose all of my iTunes music! WinDVD will not start at all now. What crummy software. I'm going to look elsewhere for a video editor. Good luck.
