To be honest, the downloading mechanism is clunky. The recordings are really meant to be streamed from the server.
You can download the recording by logging into the server… https://meeting.sinc.stonybrook.edu/
Finding your room… entering it. Going to Meeting -> Manage Meeting Information
This opens up a browser, find the Recordings tab.
Locate the recording, select the action pull down, “Make FLV”
You may have to install an Adobe Connect Add-in.
Then it has to be left to play in real time to download and convert to the FLV format.
