Adaptec Toast DVD for Mac

From Adaptec:

Toast DVD can create DVD-ROM or DVD-Video discs using a DVD-Recorder, allowing DVD title producers to create one-offs for development and testing. Toast DVD can also create an image of the DVD-ROM or DVD-Video on a hard disk drive or other storage media, such as a Syquest or Jaz drive. The image created can then be emulated or played from the drive before actually burning a DVD-R disc, saving time and money.
