The program recognizes any available CD players connected to your computer and you just have to choose one from which to create the ISO.
A progress bar, similar to that found in the download manager, lets you see what stage the project is at.
All you have to do is specify the name and location where you want to save the CD image. LC ISO proves to be very robust, despite its small size.
Another interesting feature is the speed at which it builds the ISOs, which is pretty amazing.
Do not try to make ISOs of discs with any form of copyright protection as it will simply not work.
