I need help with my DVD Burner. I have a MAD DOG multimedia 16x hooked up to my mac (ibook). And it usually works really well, but for the past few days, it has been acting up, iDVD keeps saying that I don't have a DVD Burner connected when I really do! When I hook it with my USB it works! When I hook it up with FireWire, it doesn't! Please help
