If you can live without all the channels, off-air Digital TV is just as great looking as HD Cable or Satellite service. For re-runs of TV series and movies, add a streaming Netflix account and you have a nice, and cheaper, substitute. Using Windows Media Center (which is included in Windows 7) and an Xbox360 on your TV will still give you a cable-like experience with TV listings, show recording, and more. Your digital music collection and DVDs (if ripped) can also be streamed throughout your home. Enough people have asked me about what it takes so I made a quick and dirty video about it.
