This is what worked for me when trying to download video and slides from a sonicfoundry presentation:
URL Snooper for the slides (set protocol filter to "Show All", and enter a keyword specific to the URL of the slides in the Keyword Filter; eg "640". simply jpg would probably work too but has the disadvantage that the URL's of other images on websites you visit in the meantime might get captured as well. When the video has stopped playing, "Stop Search" in URLSnooper; Select All URL's and paste it in a txt file, saving it on the Desktop with as filename.lst This file can then be loaded in
NetTransport
(
Net Transport 1.87 is the last freeware version) to batch-download the bunch.
In combination with
WebVideoCap for the video part.
