Navigation and getting started
The page is not loading correctly
Your browser has probably loaded a cached version of the website. Try refreshing your browser. If that does not work, empty the cache and then refresh your browser.
I am hearing an echo
You probably have two instances of the video player open. Check the windows menu of your browser.
The live stream is not working
You are probably watching a cached version of the webpage. Try refreshing your browser. If that does not work, clear the cache.
The video is jerky, buffers, or stops playing
Check to make sure that you are running the latest version of your browser and the Adobe Flash player. Rebooting your computer may help. If this does not solve the problem then it is likely that your internet connection is too slow. You can try forcing the player to the lowest resolution by clicking on the HD icon in the video window playbar and choosing 360p.
The audio and video are out of sync
Refresh or restart your browser, if this does not work it may be because of a server-side problem. Occasionally the audio and video synchronization will float, we monitor the stream closely and will correct any synchronization problems as soon as possible. If the problem is not fixed within a couple of minutes please send a message to the chat or blog, or email us
The sound is too soft
We use very little audio dynamic range compression on our webcasts. While the sound may be somewhat softer than other content on the internet, we feel that it is important to broadcast the true dynamic range of the performance and deliver an experience that is as close as possible to the actual sound in the hall. Most external computer speakers will have enough power to make the sound loud enough, better yet, hook your computer up to your stereo system or use your best headphones.
