I have an 80 minute iMovie I am trying to burn with iDVD. I burned the video once but there was some typos in my menus so I am trying to burn it again. I started the burn before I went to bed and it was done when I woke up. When I try to burn it again, when I wake up it is stuck on Multiplexing and Burning. I left it on all day and nothing happens. Oddly, the disk is untouched. Now, just in case, I am burning to an image file. But there is still the same problem. I tried reinstalling iDVD after deleting the preference file and I have upgraded to 4.0.1 and I have Mac OS X 10.3.5. I tried the procedure listed here also. I am baffled by this problem, I tried burning 10 times to no avail. It is interesting to note that the snowman demo works fine, probably because it is short and it uses Best Performance. My vid cannot do that, however, because it is 80 minutes long. I looked everywhere for an answer, but none of them work. PLEASE HELP!!! Oh yea, this is on my 1.5GHz PowerBook.
