I gave in and bought a standard def tuner card for my HTPC, the AverMedia M150. Media Center Edition requires an SD tuner card to enable TV features. I tried to avoid the expense, but it was totally worth it. MCE's TV features are amazing! I've used TiVo and this ranks right up there in terms of usability. I've got scheduled recording for some essential programming (Family Guy, American Dad). I'm excited to never miss an episode again!
