Media Center Streaming?

Hi all, first post.

Here is my situation:
I have 1 PC in my bedroom with K/Ubuntu and 1 laptop with K/Ubuntu. In the PC I keep all my multimedia videos, movies, mp3s, pictures etc. How do I go about streaming it wireless or with wire to my living room tv? Or even better controlling it with a control remote from my living room? I think a Media center is the correct word?

So I want to watch videos, movies and what not that I have in my pc in my living room tv FROM the living room. I dont want to bother going to the pc, hitting play and then go to living room to watch.

Alternatives are very welcome :)
