Follow the 3.1-4.1 guide in my sig below. You'll need to softmod the console to get it playing backups.
Oh and you were right to avoid youtube, the videos there on wii-hacking are full of fail.
Edit: Also, if the console is brand new there's a good chance it has a d3-2 drive which would prevent it from reading and playing backup discs. There's no workaround for this right now and you'd have to load from usb if that's the case. You can check your serial # against the list here to see.
