You are correct I read your initial download link to the ISO and it suggested using something else but required more stuff to be downloaded. I'm worried I'm going to screw my XP system up downloading all this WIN7 stuff.

So yes I just downloaded the file copied in into and burned it to DVD using my Sonic Record Now burner program but now I see that was incorrect. 

This imgburn program does something else to the ISO file to make it useable.

See I told you I knew just enough to be dangerous.   :-)
