NERO

I am trying to burn an .NRG backup image using NERO...the file is 747 megs and when i try and burn it NERO says i need a bigger sized cd. I already have an 80min blank cd in the drive. What can i do to burn this game? The game is Sanfrancisco Rush.. I am using NERO 5.09.. Is there anyway of converting the .nrg image to another image if i can't do this with NERO?
