I did so with regards from Tales from the crypt; the early seasons were great, so I have them locally. Or, at the least the better ones; some are not so good.

For this purpose I also kept list, in .yml files, for the most recent URL. Not just on youtube but also dailymotion etc...

Interestingly there are some surges of URLs suddenly being eliminated. Naturally we know the copyright mafia is trying to hinder us, the people here, but it is interesting how that works. Because ... it sometimes works. And then it does not work. Which is quite strange to me.

For instance, you can often still find new videos on youtube here, even full movies. Sometimes you can download them; then suddenly they are gone, but they were up before that for months or even years. So it is really really strange to see some videos suddenly vanishing, others being around for decades literally. Even when you'd assume these have ... "copyright issues".
