I have a DPG5 with 512mb. I am trying to burn a 90min movie in iDVD 4. On stage 4 it has been a little over 5hrs and still going. Is this normal? It gives no estimated time of completion and just shows a blue and white "candycane" bar that is moving. The activity monitor shows that iDVD is still working. It is working on a movie exported from FCE with chapter markers. Any thoughts??? Thanks.
