I just spent like 2 hours trying to burn a simple DVD from the new iDVD '08 and it would always error out. I was trying from an external USB 2.0 hard drive that I have connected to my macbook pro. For the life of me I could not figure it out. It just error out saying that it could not encode the menu, which is the very first part. I was about to give up when I decided to move the project to my internal hard drive just to give it a crack. And loo and behold, the darn thing worked!! So there you go, thanks Apple for turning what was simple into buggy. I am not that quite happy with the new iDVD and iMOVIE. They are really buggy and the external hard drive support is much to be desired.
