hello i have a problem with burning cds with my pb G4 15" 1.5 with superdrive. if i try to burn a cd, i recieve always the same error that the medium ist damaged. i tried blank discs from different manufacturers all with the same error. so i don't think its really a problem with the disks. i repaired permissions many times and get every time the same result: We are using special permissions for the file or directory ./System/Library/Filesystems/cd9660.fs/cd9660.util. New permissions are 33261 so i think its a software problem with the files mentioned above (i think they are connectet to cd-burning if i look at their names) and not an issue withe the burner itself. i repaired the disk too without result. any help would be appreciated.! thanks in advance.!
