So I try to use Wiiscrubber to scrub my iso of Super Smash Bros Brawl but it barely frees up any space to burn the iso on a DVD5 disk. I get a backup of Super Smash Bros Brawl thats about 8 GB and so I scrub it and it goes to about 7 GB. Apparently it's supposed to scrub to 4.37 GB but it's just not doing it. HELPPPPPP
