I'm probably the last person in the world to figure this out: I didn't know how to move the Channel icons around on the Wii Menu.

Here are the four steps which could really be boiled down into two:

1. Turn on your Nintendo Wii and go to the menu
2. Find the channel that you want to move
3. Point at the channel you want to move and hold A + B
4. While holding down A + B drag the channel to where ever you want to put it

The icon management is a little less fluid than on the iPhone/iTouch since you need to have a space empty before you can plug another channel into it. Managing the icons in this way is almost like a tile game itself.

Now you can move that devilishly hard Mega Man 9 onto the second of third screen so you don't feel the shame of giving up on it.
