Why do I get the error (see attached picture) and what can I do to fix this? I am using Parallels 4 with a Windows XP BootCamp VM. I have a MacPro with 2 identical DVD drives. I would like to use both drives in the VM. MacPro Early 2008, Mac OSX 10.5.7, 4 GB Ram, 2 super drives, Paralles 4.0 (3844). Thank you very much for your help. Olaf
Hello Olaf, You can use one DVD at a time. So, while you are using one DVD the other DVD will be disconnected.
