Does watching over the air HD TV require a subscription from TiVo? - what kind of tuner do you need to record digital tv to a vcr

I watch this Samsung TV receivers, which to my car without air HD channels in high definition allows. I'm looking for this particular device here: http://www.bestbuy.com/site/olspage.jsp? ... I want to buy it because I have a digital HDTV tuner, but it has 5 ports components.

Well, I think, a TiVo. His model of dual HD tuner for $ 299.99, you can see the air in high definition and save. Registration would be pretty cool, but I can not wait. So I wonder, can I buy now and get the TiVo programming on the air and HD subsequent subscriptions purchased only the registry? I do not need now for cable channels. Finally, I wish the cable andWith respect to the air, but only buy when I get that CBS, ABC, NBC and Fox in HD over the airwaves. You need a subscription to one aspect of them?
