Ah, alright. Well I found that there is a 720p copy of the video file on the server as well:
Code:
rtmpdump -r "rtmp://realaudio.service.emory.edu/EVENTS/COMMENCE/" -a "EVENTS/COMMENCE/" -f "WIN 11,2,202,235" -W "http://realaudio.service.emory.edu/clients/jwplayer5.4/player.swf" -p "http://www.emory.edu/commencement/webcast/index.html" -y "mp4:commence2012-2.mp4" -o mp4_commence2012-2.flv
So if you want a higher quality version you could download that. Maybe the sync issue would be fixed in that too.
