Just to clarify something: - ImgBurn (or any other burning program for that matter, including Blindwrite), has nothing to do with the quality of your burn. Everything is dependant on the quality of the drive and the quality of your media. All ImgBurn does is send a set of commands to the drive. It's then up to your drive to figure out what to do next. Also, CMC media is garbage. If you have any left, toss them into the bin and save yourself some pain.
