Now you're misunderstanding plain English!

That example is from the man page. The fact it contains a prebuilt ISO 
filesystem is immaterial, it's a file and growisofs is just writing a 
file to the DVD, doing no processing and not (AFAIK) verifying it's an 
ISO image.

If that does not work (and I think that improbable), try a DVD-capable 

The "=" is important. Without it, I would expect growisofs to wrap the 
file into an isofs.
