This is the RTSP link to the keynote Steve Jobs did at WWDC. How does one go about saving these now? I know StreamBox used to do it, but it's horribly out of date. Any other suggestions?

That link doesn't work for me, but try grabbing that file with wget or something like that and then opening it with your favorite text editor. It should just be a very small binary file with links to actual hinted quicktime movies suitable for various connection speeds. They may not human readable, but it is probably worth a shot. At least that is the way it used to work.

Try using SnapzPro to capture a movie of a portion of the screen and WireTap to record the audio, then use Quicktime Pro or whatever to merge the two tracks.
