I created a backup of one of my movies and set it up to create an .ISO instead of burning. Instead of creating an .ISO it created the image as an .MDS image. I am familiar with this image type as well (though Im not sure why it did not create an ISO) -- but when I boot up Alcohol 120% to burn it, Alcohol tells me that it is an invalid image type. MDS images are Alcohol 120's native image. Any ideas as to why I did not get a standard .ISO image?
