Her daughter in law, who lives on a neighbouring property, started
to study a degree in agriculture from home – but had ot give it up
because the courses resources were streamed videos online.

But part of the problem is the fact that they are videos. My experience
is that most videos add very little to the accompanying audio (unless
there's something physical to be demonstrated) but come at a huge data
cost. A slide pack + audio will adequately cover most things (and with
better resolution).
Streaming just compounds the problem because you can't download it and
watch it later.

Indeed, but Australia is a different universe. Course materials expand
to exploit anticipated resources, much as the observed exponential
growth in demand for data is just the web getting heavier as it adapts
to the rest of the world's improvements in bandwidth. Canute and the
tide spring to mind.
Video and audio are generally poor teaching media. Of course, so are
lectures.
