Hello,

today I was teaching my computer class how to burn a ISO file to a DVD. I was demonstrating how to do so with my MacBook pro running mountain lion by trying to burn Windows 7 on a DVD. I did not work, an error message appeared. I was burning Windows 7 to a new Sony DVD-R 4.7 GB/Go/120min disk. I am clearly doing something wrong. Please teach me how to do this, I have never been so embarrassed in my life.
