Since I have a HP cd burner, I downloaded the free burning software off of www.hp.com.
When I selected the .ISO for burning, the program asked if I wanted to extract the .iso data for burning. Another guy in our office uses Nero. He had to go to a menu and select that his data was from an image. I understand with EasyCD creator you can just double click the file in Windows, and EasyCD automatically extracts the data before burning. All of these examples are from Windows. I think if you want to burn a cd in Linux, you use cdrecord but I am not sure how you extract the data from the image before burning.
