First of all before using any stream recorder you need to get a stream URL
(you may skip this step when using WM Recorder and RM Recorder). To
find the URL use Packet Sniffer and URL Snooper software like free
Project URL Snooper (some stream recorders like WM Recorder, RM Recorder, Replay A/V, GetAsfStream have a build-in URL finder).

After getting the URL
http://vodcast.mit.edu/6.034/Podcast...4pod1_flat.mov
you save the .Mov QuickTime video to HD using your favorite

I've got Mozilla Firefox browser and I didn't really use the URL Snooper software here. After clicking onto QT URL I'm automatically asked to download the QuickTime video using Mass Downloader (download manager with streaming media support).
But you may use any download manager here, 'coz no streaming media support is required.

Hope it will help you to study!
