How do I stop Bitdefender scanning DVD & Blu-ray discs?

Every time that I load a DVD or Blu-ray disc, Bitdefender insists on scanning all the files on the drive, making it impossible to use the actual disc. I can disable Bitdefender Shield for an hour at a time which temporarily solves the problem, but is there a way to permanently tell Bitdefender to ignore this drive? Adding the volume to exclusions doesn't work because each disc is named differently and therefore has it's own volume.
