Alcohol 120% gives "No Disc" message after simulation

If I checked simulation and write, after the simulation, alcohol gives a “No Disc” message. I have to eject and load the DVD writer for alcohol to recognize that the media is blank and therefore able to write on. Why everytime after simulation, alcohol gives this message? I’m using Alcohol 120% 1.9.5 build 3105, Pioneer DVR109, Verbatim 16x DVD-R.

Are you trying to burn onto the correct media type?
DVD images can only be burnt to DVD & CD images only to CD.

Yes DVD to DVD.

Actually it gives a “Not an empty Disc” message.

easiest thing to do would be post a screenshot showing the error.
