I don't think it works.
Did you try making an .iso file for the video and running multiple instances of imgburn in parallel, each burning that iso to a different burner?
With imgburn free, most burners coming with a free OEM copy of a burning program and the excellent cdburnerxp being a free download also, I fail to see why anybody would pay $30 for another burning program. Let's hope you're still in the trial period. Saves you $30.
