I don't have the technical skills to do so myself but, these days, you just have to grab those videos off the web pretty quickly and get them into your own system before they're taken down. There is always a chance that the Web Sherriff (some North American guy, based in Britain, who runs a business closing down this sort of on-line thing) will intervene. The problem is that the Web Sherriff operates on the basis of " shoot-first-and-ask-questions-later". He says that he doesn'toperate this way but I've been told that he does. As you know, I'm more of a Dylan fan and, within the video-collecting circles there, not much of a video collector at all but I have built a range of contacts over the years and that's what I hear.
Usually, the Web Sherrif takes action on the basis of copyright infringement. In this case, I can't think that there are any copyright issues, so perhaps there is more to this case.
I don't wish sound paranoid here, even in a minor way, but this could suggest that someone is watching YouTube, even on a public holiday here in Britain, to try to spot these sort of things..
