Hi everyone, I have a DVD burning problem, that may be due to upgrade to Panther, or may be a Toast 6 problem, but am not sure. Trying to make backup copies of some of my more collectable commercial DVDs. I rip with DVD Backup, process with DVD2ONE and attempt to burn with Toast 6. So far I have only managed to create "Data" disks that will only fire up on the computer, so there no use, but it at least shows there's nothing wrong with the burner. When I attempt to make a "DVD-Video" with Toast, once the encoding is complete the following error message comes up: "Cannot burn DVD due to MacOS error: Result Code = - 50" I have an old G4 and have had the latest Pioneer "Superdrive" installed by a mac pro prior to installing Panther. I have subsequently installed all the latest Panther and Toast 6 updates. Would really appreciate any advice. If I cannot solve the problem I have wasted a lot of $$$. Thanks. EDIT: Apple Support site says -50 is "error in user parameter list". Anyone know what that means?
