Just don't hook it to the Internet?

Seriously - it isn't that hard. I guess I'm old school - I have an AV receiver (it serves as an amp for my speakers too!) and it let's me pick between the few devices I have. Xbox for games/BluRay, Tivo or Apple TV - there aren't very many services that aren't on one of those three. I would NEVER hook a TV up to Internet. Maybe long enough to do a firmware update, but that's it.
