I am quite proud of myself for figuring this one out - I needed to download a streaming flash video online and convert it into a Quicktime (QT). Here is the break down on how to do it on a MAC (there are several free programs you can download for windows that I was not able to try).
1 - Using FIREFOX, download and instal a FLV (flash) downloader. I believe there are two or three, but the one I used was KARBON and can be downloaded here
2 - Install PERIAN, you can download it here. Perian is a free, open source QuickTime component that adds native support for many popular video formats.
3 - Regular quicktime probably won't open the FLV file, but Final Cut Pro (FCP) will. You are all set, unless you don't have FCP.
