Build a DIY Slingbox  Blogger David Glover built a DIY Slingbox
out of the Mac mini under his television, a DV camera, and the
freeware QuickTime Broadcaster application. What's it do? In a
nutshell, David can stream live TV to any computer in his house.
The setup is a bit of a to-do, but when it's all said and done,
the quality is actually better than a Slingbox. Then again, if
you don't have all that gear but you do have a Windows PC with
Windows Media Center and a $60 TV tuner card, you can pull off
similar functionality by turning your PC into a media center
powerhouse and setting up WebGuide.
