Problems with Toast Titanium

I have a MacBook with Roxio Toast Titanium Ver. 7.1 installed, and I want to burn ISOs onto CDs and DVDs. However whenever I tell it to burn an ISO it only burns the file itself instead of all the files on the disk. For example instead of getting all the files and folders contained in the image, I get simply the file name, such as "disk.iso". I am choosing "ISO 9660" as the format, so I don't see why it is not burning it correctly. Any suggestions?

1)Open Toast and go to the "Copy" tab in the main window.

2)From the left side select "Image File" as the format type.

3)Select the image file.

4) Now you are ready to burn it with all the files and folders in it.

see above, was because you were likely dragging the ISO and burning it as a data disc.
