The Ripples in the Ether (1972) demonstrates a Philips N1500 VCR attached to a Philips G8, recording an off-air clip of Raymond Baxter. And RV Jones (1981) is seen describing how GPS works.
Some of the programmes on the RI website already look like 'found' recordings on domestic tape, the Heinz Wolff one for example (1975) is rather jittery.
Either way I can't recommend them highly enough. Shame they wont play on my smart tv.
