I think it was not just the lack of available programs but also the lack of
cheap hw that could get TV/VHS/reality onto a computer.
Today everyone has some kind of photo and or video camera and video capture
card but these things where not that cheap or widely available in "the 90s"
And when you have no video material to begin with theres also none to watch
or compress ...

I at least remember that as a kid i build my own video capture hw by sticking
more or less randomly electronic components between my
computers parallel port and the video out of my VCR.
Rather surprisingly this actually did work and i got a blurry slightly
unstable 5 shades of gray picture, horizontal resolution was somewhat crap
though due to the low speed of the parallel port ...
But then it cost nothing being build from stuff laying around ...
I then after that designed some better hw based on a real ADC and a FIFO to
improve the horizontal resolution at the expense of the vertical one, but i
never build that ...
all that IIRC of course, as this is really long ago
