There are several postings online recommending VLC Player use to save Keynote speaches. Most say this isn't possible, but it is....I've done it myself.
Here are the instructions if you don't have them.
I have no problem saving small streaming video files. However, when a large (over an hour) video is being saved, I received an error with QuickTime. Is there something I have to do to tell VLC Player the video is complete and to finish the movie being saved?[/url]
