Search for Netflix in the App Store or the Android play market.... There are a bunch of third party apps.. Especially on android (but none of them actually stream Netflix, they just allow you to manage your queue etc)
One of the devices in my house is an older blu-ray player that has the Netflix streaming ability, but it can only play stuff from your queue! So, I have to put stuff in my queue I if I want to watch it on that tv. Otherwise, though, doesn't seem so useful when you are just streaming.
