I just downloaded a program called ORB from
http://www.orb.com/. The requirement for live TV is that you have a compatible TV tuner on your home PC. They state they only support certain tuners but my works flawlessly. I have a ATI 9800 PRO AIW at home. I installed ORB and had access to live TV, videos, pictures, and even my web cam with sound (home brew home security system

) immediately from my Q. Of course you get a better streaming depending on your location and connection speeds. Even if you don't have a TV tuner, the web UI is not that bad to access pictures, videos, etc. You can also setup TV recording to your PC. So now I have NES games, ripped movies, and live TV.
Q rocks.
