Am I missing something with eyetv? I don't see where you have an ota tuner option. You need a cable or satellite box. That makes it a very expensive analog video recorder.
This seems to be one area where Apple and people who develop for it have no interest in providing a workable solution. Windows Media Center is built in and compatible with a wide variety of tuners and other video recording hardware. It's easy to setup and use. It's something I miss after moving to OSX. I liked having a small window on my screen with live ota or playback of shows I missed, while I worked on other things.

Hmmm, just noticed the UK site has newer / more hardware than the US site. I'd love to see eyetv 3 available in the US.
