Nah, it's HDCP that's cracked. You can grab HDCP strippers (or rather, "splitters"/"signal multiplexers" that happen to strip HDCP) for cheap on alibaba and the likes. From there, all you need is a HDMI framegrabber or if you want the best possible quality, an SDI converter and a BlackMagic Decklink SDI capture card. That's a few hundred bucks.
