Iso file to vcd?

How can I convert a iso file to a vcd, so I can burn it on a cd-r?

what is in the iso file? Generally you can see the contents with a program like IsoBuster or WinRar and extract it. Or, you can directly record the ISO file to the CD-R (you may want to try a CD-RW first, just so that you don’t mess up a blank). Depending on the software you use, the option to burn an iso file is called diferently, but it tends to have something like “image file” or “iso” in the title of the project.
