Windows media encoder.
I use Orb and I love it, and, it's free. The only downside for the streaming tv is that it's not live. As a matter of fact, my listings are on a 6 hour delay. I just use it for streaming recorded tv, photos, music, and videos... good stuff.
a few days ago i had a conversation with myself, where i asked "how can i stream the land cable tv signal, from one computer with a tv tuner, to any computer, in house or over the internet?" (reason: just for the fun of it and to add it to the list of "apparently-useless-things-i've-done-but-that-might-be-handy-some-time")
the answer, after some search, came in the form of Unreal Media Server 5.0 (link)
it's a software-only solution for Windows, free (to a max of 15 concurrent connections), seems to be well documented and easy to use, and even allows to change channels (requires IIS) !!
i haven't tested it yet, but i hope to have some spare time to do it, shortly
has anyone tried it?

I have a slingbox, and I use it in my car. It flips my friends out. Won 2 car shows in my division so far and I know the cable in the car was a huge point getter for me.
Sling box all the way
I'll second the slingbox idea. My father got one last year and it's sitting stashed away in a corner of their house with a full cable connection. I'll use it on the laptop to watch something that I don't get here at my house but will also stream it in the card.
Just upgraded to an LG CU500 using Cingular's high speed network and it works pretty well. Was previously just using EDGE and I could really only stream audio, no video.
