Spycake definitely has the cheapest answer. I'm a big chromecast fan though. You could technically use it to watch other things through other apps. It's only $35.00. You just set it up through the chromecast app and it connects to your wifi. When you want to watch something, you just look for whatever you want through that app (youtube, sling tv, netflix, hulu), and click the cast button and it sends it to your tv. It's pretty slick. No extra remotes or anything. http://www.google.com/intl/en/chromecast/tv/#?discover
