Black Screen is usually an indication of a bad rip. If you no longer have a playable disk to rerip, you'll have to find yourself another copy to avoid piracy and breaking the rules of the site that you accepted 30 min before making this post.
EDIT: OK. I saw your other post where you stated you modded your system using a different guide first (of which, linking external guides is against forum rules. You'd have know that if you read the rules before accepting them).
So which is it: softmod any wii? or the crap fail-tube video?
And none of this negates what I said about piracy in the first line of my reply.
