I'm running Parallels 6 on IMac Snow Leopard with Windows 7 Ultimate Guest OS. Everything is working with the exception of my 3 DVD Drives. I've configured them in Devices and they show up in explorer, however, when I try to use them to watch a video, or use programs such as DVDFab, DVDneXt or Xillisoft copy, the drives recognise the disc but will not do anything else. All they do is continually scan the drive and not read any other information. Any suggestions would be very helpful. Thanks
