And there are many ways to capture streamed video into a file.
If you use Firefox for a browser, you might try installing the Downloadhelper plug in. I’ve had good luck using it to capture to an MP4 or AVI file streaming videos from various sites.http://www.downloadhelper.net/
I’ve got no idea if it is compatible with whatever protocol is used to stream these videos, but it’s worth a shot, being free and all. (I’ve got no connection to it, just am a satisfied user).
If it doesn't work, I've heard good things (but have no experience with) Applian Software's
"Replay Media Catcher" and "Replay Video Capture." These aren't free, however.
Christian -- my preferred solution would be for you to just come by the house every so often, and do the routines in person. I've got a room you can sleep in, and my wife is a good cook. (I'm working on being an honorary Fat Brother, if you know what I mean).
Seriously, your workshop at the Genii convention was outstanding (as was Miguel and Dani's). Stong, deceptive magic that was entertainingly performed. You can't ask for better than that.
