What I'd really like to do is tap into all of the Discovery, History Channel, type shows via the Internet and download them onto my TiVo.
Is it possible without putting the Geek Squad on retainer?
Most of the video stream sites do not allow actual downloading for later viewing.
iTunes and similar sites allow you to download (for a fee). But such downloads are time-sensitive; that is, they expire (erase themselves) after a certain time period.
