Assuming you've recorded it on some kind of DVR that doesn't allow copying and pasting, you could invest in a device that can record via HDMI in real time (common for video game consoles). They're typically a bit over $100 or so, and from what I've read, function quite well for getting shows onto the computer with little hassle.
Or just record it on a VHS tape and buy a cheap A/V->USB cable

we're working on making that happen!
and that was on Wednesday, so there's hope it'll be replayed and that we'll be able to get another round of people taping it.
