ATI tv wonder 650
i own one, its absolutely perfect.
does HD and all, though i dont personally get n e channels in hd.
anything made by ati is perfect though. lol
not through the tuner
you'd need a cable box with hdmi output, a video capture card with dvi in, and an hdmi to dvi cable.
i'd honestly get an hd timeshift box from my cable company if i were you
there's no cheap fix to do it with a computer, and stay digital
