First let me ditto the protected HD content concerns. I built a Windows Media Center box a few years ago. I never got around to using when my cable company called me shortly afterwards announcing they were offering an HD dvr box. Another reason I abadonded the project was the cost of the video and audio cards, which would have doubled the price of the pc. Two things have made me reconsider the idea: my cable dvr is really limited in space and I'm constantly deleting stuff I'd like to keep, and here in RI, because of a dispute between the cable co and the local broadcasters, I can't get anything on CBS or Fox in HD, which stinks because I love football. I didn't even get the first 2 Patriots Super Bowls in HD, which is a huge deal to me! Thankfully, ND is on NBC, so I get those in HD. The issue hasn't been resolved in 3 years and probably won't be anytime soon, so every football season I look into the price of an audio card and HD tuner once again.
