Burning a DVD using Alcohol 120%

I need help with burning a dvd using Alcohol 120%, with the help with the people of these boards, I figured out how to format a dvd, but when I go on to Alcohol 120%, “Image Burning Wizard” and follow the steps, I eventually get to the menu that says “Start” I click it and a window appears telling me that I need to inset a disk, but on the menu, it tells me that I have a Blank DVD in the DVD Burning drive. It used to say that I had an unformatted Disk (Untill I formatted it) can anybody help me out to get it to accept that I have a Blank Formatted Disk inserted?
