I have this and it does a decent job if you've got a high horsepower machine as there is no hardware encoder. It only handles over the air digital. It has both and analog and a digital tuner and is much better than the board based KWorld products. The antenna it comes with works pretty well for me if I place it near a window facing the direction of the source signal but you'd probably want to invest in a better antenna. It does it's job pretty well, but I'd suggest looking elsewhere if you are looking for a tuner for a good HTPC setup though.
