Wii ISO mage burn Questions ECT Errors

Ok I tried googling for answers and now I'm stuck at a halt, and I keep getting errors and have no idea what i'm doing wrond or if i'm even doing it right
I'm using DVD+R 4.37GB and I have never done this so i'm assuming i'm doing it right, and I'm not even sure if I extracted the Wii ISO correctly
I have NSMBW and I extracted "to HERE" by highliting all of them and then in made a single a file called
"NewSuperMarioBrosWii(supercompress)"ISO image file 4.37GB and then I grabbed this ISO file and used ImgBurn and clicked
"Write to disk" and checked "verify" and set the Swrite speed to"x1" and copies "1" and of course chose NSMBW and then clicked on "Write" but once I waited about half a hour for it I got this message with ERRORS ect followed by a females voice "Oh no" and once that happen I tried doing it again and the "write" button is faded out? so any ideas on what I might be doing wrong?Thanks in advance!
