I just have a couple of questions. First off, a stupid question. What is an IOS?

Second question, do you have a specific means by which you want us to record our videos? This is my first time doing anything like this, and I just want to make sure I know what all is needed and expected.

I can't answer the second question, but an ISO is either playing the game on an emulator or loading it onto your wii from a USB.

An ISO is an artificial copy of the game that is used via a USB and USB Loader. It is banned due to unfairly fast load times and it being an unofficial version of the game.
