It's easier than you think. Look at Macrovision. Look at the EURion constellation. All you have to do is make your secure video path emit some kind of signal not immediately apparent to human eyes. In a post-general-purpose-computing world, you can just make consumer-grade devices respect these signals and refuse to record and make professional-grade equipment both insanely expensive and specifically traceable.

I agree, but my point is this - If you can see it or hear it, then you can record it. Sure, the recording device you'll need in the future might be insanely expensive/rare/illegal, but there's also a lot of money in piracy.
