If you are in OS9, run UVI-Extract first. Click on, "Insert Disc," and select your format and then insert your disc. If you are in OSX, your disc may mount to your desktop. If so, simply launch UVI-Extract and select your disc from the Finder column. If your disc does not mount, Mac OS will prompt you either to "Eject" the CD or to "Ignore" the CD. Select "Ignore" and then launch UVI-Extract. In the "Disc" pull down menu, select, "Search for Sampler Discs."
