Hi, I am very interested in hearing from someone using this. My understanding is that with this patch you can open iDVD3 on a G3 or G4 Mac, set up your DVD, encode your video to MPEG2, and have the "whatever it is called file" all ready, so you could put it on an external firewire drive and then bring it into any Mac with a SuperDrive and iDVD3 and burn your disk? Or can the "whatever it is called file" be used with Toast to burn on any external firewire DVD burner? Thanks for any explaining or help on this. As you can tell I have not made any DVDs yet. Craig
