Well, so when i was formatting my DVD-RW, it said that it had 4.38 GB. After the format was done, it had 4.20 GB. I was like, WTH. So I need to compress a Mario Kart Wii . ISO (which is 4.37 GB) just a few MB's back. How can you do this? And could you make the .CSO back into a .ISO without making it back to its original size? And the Title+Description? Thanks again my fellow Tempers...
