Toast 10 fails every time when writing lead out. I have trashed all the preference files and tried 3 different brands of media with the same problem. I can use Apple's built in burning system and everything works fine leading me to believe the problem is directly related to Toast. I have a Mac Pro with a GGW-H20N Blu-ray burner connected to the SATA connector where the 4 th hard drive would be. This setup has worked fine with Apple's burn engine. Any ideas?
