I don't understand how to burn a disc from a disc image. Do I navigate to a certain file and click on it? Is that file in a particular folder? Is there a tutorial on how to burn a disc from a disc image?

 thanks,

A DVD or a Blu-ray ?

A bluray. I have successfully burned Bluray discs by clicking on burn disc. What I would like to do is create an image so I can burn more copies later.

Once you've clicked teh Burn image button, select Disk image (Folder) and browse via the Source button to the BDMV folder on your hard disk. Hit Burn.
