No, there is no such issue with CD-R drives. This is strictly Apple's decision to make their iDVD software look for an internal drive and refuse to burn a DVD if it doesn't find an internal drive. Prior to iLife '04, it wouldn't even let you author a DVD. Now you can author on one machine and move the project to another machine that has an internal DVD burner to complete the final step. If you were unable to burn a CD using an external drive, it's another issue. Shirley On Friday, December 17, 2004, at 09:05 PM, lilyplant wrote: > Got it.
