I am trying to burn a 45 minute home movie created in iMovie. Nothing special, 8 chapters, a few transitions, opening and closing templates, a little bit of imported music from iTunes. I have exported it to iDVD, chosen magic DVD to keep things easy. Selected my template, moved the movie accross, clicked to make DVD. The rendering goes fine, takes about 45 minutes to 1 hour. However, so far the burn stage has taken 11 hours, and is still going. I am using an Imation DVD-RW 4x DVD, and a USB Lacie Porsche designed external DVD burner, because the drive in my MBP will not recognise the Imation DVD. This burner is connected through a Belkin USB hub, and is being powered through the hub. Activity Monitor says that both Thumbnailserver and Encoderserver are not responding. This is the second attempt at burning this movie with the same results. The disc I made yesterday took just as long. When it had completed and ejected iDVD was still running, I can't remember exactly what process it said was running, but I clicked cancel amd it moved to cleanup, did nothing for ages, at which point I force quit. The disc made yesterday did work, but the opening menus are very jumpy for a few seconds. I am open to any suggstions as to what is happening here and how to speed things up.
