A lot being discussed here is shooting over the top of my head. May I pop in and ask? I am a comcast customer, can I build a PC and get a cable card and tuner and get content just like the cable HD box? From what I gather from all your comments is that I cannot?
You can, using Windows 7 and a cablecard tuner from Ceton, SiliconDust, or Hauppauge. You can also use the Xbox360 as an extender (STB) on secondary TVs.
is a great place to start for this.
