^^ Yep, that covered it, I have some extra stuff too:
You dont really need the icon= line. Its only for loading extra icons, or a specific icon from the exe file. And one more very important thing he forgot is:
Save the file as "autorun.inf". And write the autorun.inf to the ROOT folder of the cd/dvd!!! this is very important, as windows checks for this file on the root folder only.
eg:
Right -
<cd>:\autorun.inf
Wrong -
<cd>:\Program\autorun.inf
But you can have your program anywhere. If your program is within a folder, use
[Autorun]
open=foldername\something\program.exe
Dont mention your drive letter in the path, since drive letters differ from comp to comp.
