Hi Jacob,
You're getting < HTTP/1.1 500 Internal Server Error when making this request.
This means somewhere in /opt/kaltura/log/kaltura_api_v3.log or /opt/kaltura/log/kaltura_apache_errors.log there is a fatal error to find and fix. The request you posted reached node1.servcast.net, look at the logs there to find the error, then I can help you fix it.
