Poweriso, Ultraiso, Magiciso etc. will allow you to edit iso files. However, the trial versions will limit the size of the edited iso file you can save to a max of 300mb. If you've got a licensed copy, the worlds your oyster.
Here's what to do. Download the legit iso from TorrentG's link and load it into your iso editor.
From the list of contained folders / files select the sources folder. Then scroll down and find the ei.cfg file and delete it.
Save the modified iso file and then burn to disc. You now have an "opened" dvd.
