With MythTV (www.mythtv.org
) you can stream TV through you wireless from your MythTV box. The catch is that MythTV is a Linux app. There might be something similar for Windows.
I've used a knoppmyth LiveCD on my i9300 to watch TV from my MythTV box. Only problem is the video looks terrible if I go full screen on my WUXGA and if I leave it windowed it's super tiny.
