I rip all my movies to mpeg4 and serve them on my Samsung DVD player via Samsung PC Share Manager.
It's a lousy solution, but serves my purposes. I'm sure I can serve media right to my tv, but I'm too lazy to bother with it. All I want to do is watch movies with it.

Peter's solution is much more elegant being as you're using a Mac. I'm not.
You can move your Apple tv wherever you want it, too. I don't have that functionality.
