From your PC to your TV, by way of your Wii. That rhymed and was annoying. I apologize. But seriously, you can play almost any video that's on your computer right now using your Wii; it's not hard. Your Wii is hooked up to your network via WiFi and so is your computer. All you need to do is share the video from your PC and open it on your Wii. Sharing the video is easy - Windows comes with that ability built-in.
